Structural Damage Identification Based on Principal Curvatures of Mode Shape
Authors: Gorgin Rahim , Wang Ziping
Published: January 2021

This paper presents a procedure for damage identification and characterization on plates, based on the principal curvatures of their first mode shape. Each mode shape represents the displacement of the structure at its corresponding natural frequency. Since, variations in the geometry due to cracks or material property degradation, make changes in the mode shapes of the structure, such changes can be used for damage identification methods. The presented procedure only requires the first mode shape of the intact and damaged structure. It is shown that the principal curvatures of the surface defined by the first mode shape of the structure, are sensitive to damage and the maximum principal curvature can be used to highlight damages on the structure. The performance of the developed method is firstly evaluated using finite element analysis. To this aim, the procedure is applied to highlight both single and multi-damages in different locations of the plate with different boundary conditions. It is shown that the location of the maximum curvature variation coincides well with the location of damages and the amount of the maximum curvature change can be used as a parameter to describe damage severity. The accuracy of the proposed method is also experimentally verified by test on an aluminum plate and it is demonstrated that the proposed method remains effective even in experimental condition when only a limited number of measurements are available.
A Dynamic Investigation of the Impact Failure Analysis of the Friction Plate in a Planetary Transmission System
Authors: Li Shenlong , Zhou Shuhan
Published: January 2021

A clear understanding of both vibrations and the impact forces of planetary transmission systems is very helpful for decreasing impact failures of their friction discs and preventing serious accidents of the system. This study presents a multibody dynamic (MBD) investigation based on a commercial MBD software to predict the vibrations and impact forces of the friction disc in a planetary transmission system. In the MBD model, the radial clearance of the planet bearing is formulated, as well as the backlash between the outer gear teeth of the ring and friction disc teeth. However, the previous works in the literature only considered single radial clearance or backlash. The influences of the radial clearance of the planet bearing and backlash between the outer gear teeth of the ring and friction disc teeth on the vibrations and impact forces of the friction disc in the planetary transmission system are studied. The results give that a smaller radial clearance and backlash can be useful for decreasing both the vibrations and impact forces of the friction disc in the planetary transmission system. The MBD method can be applied to predict the vibrations and impact forces in the planetary transmission system as well.
Free Vibration of Axially Moving Functionally Graded Nanoplates Based on the Nonlocal Strain Gradient Theory
Authors: Li Cheng , Wang P.Y. , Luo Q.Y. , Li S.
Published: January 2021

Using the nonlocal strain gradient theory, we explore vibration behaviours of initially bidirectional tensioned functionally graded nanoplates with axial speed. The governing equation of motion can be obtained based on the differential type of nonlocal strain gradient constitutive relation, which characters the dynamics of nanostructures containing kinematic relation. The simply supported boundary constraints on four sides are considered and subsequently the numerical results are determined. It shows that natural frequencies of axially moving nanoplates decrease when increasing the axial speed and the nonlocal parameter. Hence the nonlocal and kinematic factors cause the natural frequencies to decrease or, weaken the equivalent bending rigidity. On the other hand, natural frequencies increase with an increase in the axial tension and material characteristic scale. Hence the strain gradient and tensile stress factors cause the natural frequencies to increase or, strengthen the equivalent bending rigidity. In addition, the natural frequencies get higher with a larger aspect ratio of the functionally graded nanoplate. The larger one between the nonlocal parameter and the material characteristic scale plays a dominant role in the softening and stiffening mechanisms of the nonlocal strain gradient effect. In case of the same magnitude of the nonlocal parameter and the material characteristic scale, the softening and hardening phenomena disappear. The equivalent bending rigidity neither increases nor decreases in such a situation, and its value degenerates to the classical one.
Planar Dynamics of a Motorcycle: Influence of Vibration Isolation System Nonlinearity
Authors: Kaul Sudhir
Published: January 2021

This paper investigates the influence of the nonlinearities of a vibration isolation system on the planar dynamics of a motorcycle. The use of a nonlinear isolation system is often necessitated by design and packaging constraints. Although the use of a vibration isolation system is uncommon in motorcycles, it is used in some cases to enhance ride comfort by mitigating vibrations transmitted to the rider due to shaking forces. In such cases, the handling of the motorcycle can be influenced due to the coupled dynamics of the rear unsprung mass and the swing arm. In this paper, a stochastic analysis has been performed by using the statistical linearization method to specifically examine nonlinearities associated with the vibration isolation system. An eight degree-of-freedom planar model has been developed, and each isolator is represented by a modified multi-axial Kelvin-Voigt model. It has been observed that the model developed in this study can capture the coupled dynamics between the rear suspension and the vibration isolation system. Results indicate that the nonlinear design of the vibration isolation system can be useful in enhancing ride comfort in the lower frequency range without an adverse impact on handling. Furthermore, it has been observed that the parameters associated with the nonlinear vibration isolation system can be tuned to enhance ride comfort while meeting the design requirements of spatial dynamics.

PROBLEMATIZING BLACK FEMALE CHARACTER AS MOTHER FIGURE IN ADAPTATION OF “THE CURIOUS CASE OF BENJAMIN BUTTON”
Authors: Ariesia Indira Vita
Published: January 2021

This research examines how the movie “The Curious Case of Benjamin Button” constructs the character of Queenie as mammy stereotype and the accounts of her presence in this adaptation. By applying the semiotic theory of Roland Barthes, this research analyzes mise-en-scene examination to find the mammy stereotype constructed in the character Queenie by looking at the history of slavery in America. Then, in order to find the account of Queenie’s presence, this research uses the adaptation theory of Linda Hutcheon. Thus, this research finds that the movie constructs mammy stereotype, that has been ingrained in the history of slavery in America, in the character Queenie through mise-en-scene, specifically in the figure behavior of Queenie. Moreover, the presence of Queenie in the movie challenges the stereotype by showing the significant role of mammy in a parent's abandonment of a white child. The presence of Queenie makes this movie as a process and a product based on Hutcheon’s adaptation theory. As her presence telling the story in variation and paying tribute to the short story, the movie represents Queenie to contest the short story point of view towards black, especially a black woman.
The Construction of Edward Snowden as a Whistleblower in the New York Times and the Washington Post and How It Represents American Freedom of Speech
Authors: Nugroho Cahyo Adi
Published: January 2021

This article employs the media narratives and semiotics analytical approach to examine how Edward Snowden was constructed in online publications of the Times and the Post as two major national newspapers in the United States. The analysis finds that both media successfully construct Snowden positively as a new kind of leaker and as a hero in the sense that he brings back the importance of freedom of speech as a living myth in the United States. He is still viewed as a hero despite his moving to Russia, the political enemy of the United States. The analysis also shows that both media perpetuate the myth of free speech. They construct Snowden’s action positively as a new method to give people courage to criticize the government.

Published: January 2021

Quatorze bibliotecas universitárias foram investigadas, especificamente em suas áreas de acervo e de leitura. Foram realizadas leituras de iluminância destes ambientes quanto à iluminação artificial, tendo sido avaliados através dos Requisitos Técnicos da Qualidade do Nível de Eficiência Energética para Edifícios Comerciais, de Serviços e Públicos (RQT-C), e conforme a norma brasileira de iluminação de interiores NBR ISO/CIE 8995-1. Foram criadas maquetes eletrônicas das edificações visando a simular contribuição de luz natural e a analisar entrada de ganhos diretos de radiação solar no interior das bibliotecas. Adicionalmente, dados de radiação solar incidente foram contrastados com o desconforto causado pelo ofuscamento da visão de usuários. Os resultados mostraram que os sistemas de iluminação apresentaram pequenos desvios a serem corrigidos, oportunizando soluções de retrofit. As análises demonstraram que os sistemas de iluminação das bibliotecas estudadas possuem baixo desempenho. Apenas oito ambientes de acervo e um ambiente de leitura obtiveram iluminâncias médias superiores ao recomendado. No que toca à incidência da radiação solar direta no interior das edificações (carga térmica), o controle da incidência mostrou-se necessário para manter o conforto luminoso e se evitar depreciação do acervo.

Published: January 2021

À medida que aumenta a conscientização da população a respeito da adoção de ações sustentáveis, aumenta também a cobrança aos órgãos públicos por políticas ambientais eficientes. Embora exista legislação que trata da compra de itens sustentáveis na administração pública, os órgãos públicos ainda estão em fase de adequação e há uma baixa adesão dos servidores públicos por motivos diversos. Assim, este estudo tem como objetivo construir e validar uma tecnologia educacional no formato de cartilha com a finalidade de disseminar conhecimento a respeito da compra socioambientalmente responsável, utilizando ilustrações e linguagem de fácil compreensão. A pesquisa está dividida em três fases distintas e compreendeu um estudo de desenvolvimento metodológico através da abordagem de métodos mistos. Na primeira fase foi realizada uma revisão bibliográfica sistemática através da revisão integrativa e um diagnóstico situacional através de uma pesquisa exploratória com abordagem qualitativa que utiliza o questionário como ferramenta para a coleta de dados junto aos servidores do Instituto Federal de Educação, Ciência e Tecnologia do Rio de Janeiro com a finalidade de identificar as dificuldades apresentadas na realização de compras de itens sustentáveis. A segunda fase da pesquisa abrangeu a elaboração do conteúdo, das ilustrações, da aparência e da linguagem da cartilha intitulada “Vamos pensar no planeta? Um pequeno gesto pode fazer uma grande diferença”. A terceira fase da pesquisa consistiu na validação da cartilha por quinze juízes de linguagem, conteúdo e aparência e posteriormente por dezesseis representantes do público alvo. Para tal utilizou-se a abordagem quantitativa através da Escala Likert. Pretende-se disponibilizar a cartilha por meios digitais.

O licenciamento ambiental tem sido objeto de diversas críticas, destacando o excesso de burocracia e o alto grau de subjetividade do processo. O objetivo deste estudo é analisar dois processos de licenciamento ambiental referentes às rodovias BR-116 e BR-392, conectando as cidades gaúchas de Porto Alegre até Pelotas e de Pelotas até Rio Grande, conduzido pelo Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis (IBAMA). A pesquisa é do tipo documental e analisou o licenciamento ambiental de dois trechos rodoviários, enfocando a cronologia das emissões das licenças e os fatores que afetaram o trâmite dos processos. A abertura dos processos nos trechos de Porto Alegre até Pelotas e de Pelotas até Rio Grande ocorreram em agosto do ano de 2000 e em dezembro de 2002, respectivamente. A licença de operação para o trecho de Pelotas até Rio Grande ocorreu em abril do ano de 2014, 13 anos e oito meses após a abertura do seu processo. Para o trecho de Porto Alegre até Pelotas, em 2019, ano de análise dos processos, a sua licença de operação ainda não tinha sido emitida. Esse longo tempo para emissão das licenças ambientais reflete a complexidade do instrumento e pode ser explicado pelo grande número de órgãos envolvidos no processo.

WASP DAN IDENTITAS AMERIKA
Authors: * Eko Rujito
Published: January 2021

There have been abundant of studies on White Anglo-Saxon Protestant and its role in shaping American culture. The assumption that America is an Anglo-Saxon Protestant nation is not entirely wrong, to certain extent, it is even indubitable. Anglo-Saxon Protestant culture and ethics have shaped America the nation it is today. This cannot be separated from the fact that the first settlers were people with Anglo-Protestant background. Through more than two hundred years of immigrations, however, when people from other parts of the globe with different cultural background and religious beliefs flooded America in huge number, this core culture did not vanish. It survived and was embraced by the majority of Americans. This paper tries to scrutinize the way the WASP identity became American identity. To do this, there are three basic ideas related to the WASP that need to be explored; the Anglo-Saxon ethnicity, Protestantism, and Anglo-conformity. In the first part it will try to investigate the significance of Anglo-Saxon ethnicity and the meaning of being an Anglo-Saxon. The second part will deal with very core of the WASP, Protestantism. In this part, this paper will answer the question on the role of Protestantism in shaping WASP identity and American identity. The last part is a discussion on the process of assimilation experienced by immigrants with non-Anglo-Saxon Protestant origins in order to be acknowledged as Americans.
