Experimental Investigation and Optimization on Friction Stir Welding of Nylon 6A Using Taguchi and ANOVA with Microstructural Analysis

Friction stir welding is an environmentally friendly process of joining due to the nonusage of flux, or any shield gas, and it does not produce any harmful gases when compared to the joining process of fusion.Therefore, this article proposes an experimental investigation and optimization technique for studying the process of fsw on nylon 6a or polycaprolactam polymer composite plates.Specifically, the influence of input operating process parameters such as tool rotational speed (trs), feed rate, and pitch values on the output response parameters like ultimate tensile strength (uts) and hardness of welded joints is examined.In addition, l 27 orthogonal array of taguchi approach is employed for the optimization of design experiments of fsw parameters.The experimental setup is carried out with various process parameter combinations like 500 rpm, 1000 rpm, and 1500 rpm as trs, and 30 mm, 40 mm, and 50 mm as feed rate by varying the pitch values as 1 mm, 2 mm, and 3 mm.Further, the analysis of variance (anova) is also employed for finding the significant parameters of input process using the regression analysis equations.Finally, microstructural analysis is used to assess the mixing or dispersing uniformity of composites effectively.

Application of Polymer Nanocolloid Preparation in Stability Analysis of Motion Mechanics

Nanomaterials are widely used in various fields because of their own advantages.When the particle size of the material is reduced to the nanometer level, it will lead to new characteristics of acoustic, optical, electrical, magnetic, and thermal properties.This will greatly enrich the research content of the material and is expected to get new uses.Therefore, the preparation technology of nanomaterials is one of the current research hotspots and has broad application prospects.At present, the most commonly used preparation techniques are hydrothermal method and sol-gel method, but not all crystals grow in a hydrothermal environment, so this paper adopts the sol-gel method for preparation.However, in the preparation of nanocolloids, agglomeration often occurs between colloidal nanoparticles.In order to avoid the agglomeration between particles, this paper adopts an appropriate method to disperse the particles.In order to further explore the stability of nanocolloids, the colloidal film material prepared by the cadmium sulfide (cd s) sol method was used as the research sample.It also proposes a sol preparation method incorporating ultrasonic waves and further discusses the kinetic characteristics.The research results show that the sedimentation velocity of 1 nm cadmium sulfide nanocolloids in water is 1.3 × 10−12 (m/s) prepared by colloid of cadmium sulfide.

Free Vibration Analysis of Thick Rectangular and Elliptical Plates with Concentric Cut-Out

This research paper deals with a numerical method which is modified and applied, by the authors to derive an eigenvalue of a thick plate having cut‐out in which geometries of plate and cut‐outs are different, through a deflection matching condition by including shear deformation and rotary inertia effects, with less computational efforts and high accuracy.The modified independent coordinate coupling method (iccm) is validated with fem package (ansys) and applied to know the change in eigenvalues for a plate with cut‐out by varying various parameters like aspect ratios, cut‐out size, and thickness ratios.Trigonometric functions considered at the boundary level conditions of a simply supported plate should be satisfied.Free vibrational exploration on a thick isotropic plate with various aspect ratios and an elliptical plate with various sizes is carried out through the modified iccm.Independent coordinates are applied for a plate domain and for a hole domain individually followed by equating the deflection condition of hole and plate, a reduced mass to express with cut‐out from which eigenvalues can be obtained.The deflection matching condition facilitates the analysis even though the geometries of plate and cut‐outs are different.

Effect of Reinforcement on Tensile Characteristics in AA 5052 with ZrC and Fly Ash-Based Composites

Aluminum alloy 5052/zr c/fly ash composites’ tensile properties are changed by the addition of reinforcements and thermal exposure, according to this study.The precipitation hardening of samples manufactured with various weight percent of fly ash and zirconium carbide was employed to improve the properties under thermal circumstances.The tensile properties of reinforced and heat-treated specimens were studied in a series of scientifically-designed experiments.Tensile strength and yield strength rise up to 200°c, after which they begin to decrease slightly (i.e., 250°c) based on the results of the research.Adding reinforcements and exposing the composites to heat increases their elastic modulus which decreases the percentage of el of the composites substantially.Several factors contribute to composites’ increased strength and elastic modulus, the diffusion process, temperatures, and reinforcement composition.It is also possible to manufacture hybridized composite mechanisms for numerous automotive and aviation industries utilizing optimization studies, which interpolate the findings of several sets of parameters to make the process easier.

Structural Classification of Basalt FRP at High Temperatures

In this study, two different temperatures are considered to verify the mechanical response of basalt fiber‐reinforced polymer specimens.Initially, fibers are subjected to 300°c temperature for 4 hours and 600°c temperature for 2 hours in an electrical muffle furnace effectively.Later, laminates were prepared with these fibers and machined into test strips to verify their mechanical properties by conducting tensile and flexural tests.These laminates were compared with specimens prepared with normal fibers, i.e., fibers without temperature treatment.Moreover, the ductility and elastic behavior of the basalt fiber‐laminated specimens are studied to figure out the possible structural applications.The residual stress of specimens subjected to 300°c temperature under tensile loading is about 84%, whereas for 600°c temperature, it is only 13% of maximum stress.A similar trend has been observed for specimens tested under flexural loading condition.Hence, it is concluded that the basalt fiber‐reinforced polymer laminate can withstand and depict satisfactory results up to 300°c elevated temperature irrespective of time.
