Stress Distribution Properties in Adhesively Bonded Beams
Authors: He Xiao Cong , Wang Yu Qi , Cun Hua Ying , Yuan Sheng Wan
Published: May 2014

The stress distribution properties in a single lap-jointed cantilevered adhesive beam have been investigated using three dimensional finite element methods. Finite element solutions of the stress distributions in the adhesive layer have been obtained for three typical boundary conditions. It was found that the stress concentrations are confined to a very small region near the free ends of interfaces between the adherend and the adhesive layer while the centre region of the adhesive layer is mostly stress-free. This suggests that the first failure may be expected at the free ends of interfaces between the adherend and the adhesive layer. This also implies that the adhesive material near the free ends of the adhesive layer is mainly bearing the load being transferred through the adhesive joint. The analysis results show that by choosing suitable boundary condition, the bending effect can be reduced and the strength, fatigue life and reliability of the bond can be improved.

Authors: Song Xin Nan , Jin Ju Lei , Wang Yu , Li Xiang Long
Published: May 2014

Based on the determination of the equilibrium surface tension for anionic surfactant SDS and non-ionic surfactant TrionX-100 under different concentrations, the two surfactants continuous boiling test and the SDS for the hydrolysis tests were carried out. Objective is to analyze the diminishing process for active ingredient of the surfactants. Results show that the liquid with surfactant is capable of reducing the surface tension. With the increment of surfactant concentration, the surface tension decreases gradually, and the surface tension is minimized under the critical micelle concentration (CMC); When the concentration lower than CMC, the surface-active of TritonX-100 presented is stronger than the SDS. At continuous boiling experiment, the thermal stability of TritonX-100 solution is better than the SDS. When the SDS aqueous solution is in the sealed environment with set temperature and the continuous boiling environment under experiment situation, the active ingredients of SDS solution will change and the equilibrium surface tension will be undermined. Owing to the chemical losses, the inherent characteristics of solution perform dramatically different from the original one during boiling experiment, which includes the hydrolytic destruction and micro-layer pyrolysis chemical effects.

Authors: Fan Meng Hua
Published: May 2014

118 Q-s curves of piles cast-in-situ with expanded branches and plates bearing pressure load were fitted via trendline of Excel. Bearing capacities on 51 of the 118 piles were forecasted. 12 Q-s curves of anti-pulls piles cast-in-situ with expanded branches and plates were fitted. Through the above work, the author found that order 3 polynomial fitting model is the most reliable model for fitting Q-s curves of piles with expanded branches and plates when bearing pressure or uplift load. In order to improve the accuracy and reliability of the fitting and forecasting, multi-model should be used.

Authors: Wang Zong Shen , Guan Yan Jin , Zhong Chong Kai
Published: May 2014

Constrained groove pressing (CGP) is a newly developed severe plastic deformation technique for producing ultra-fine grained sheet metals. In this study, the effects of friction on tensile properties, microstructure and strain distribution of commercially pure Al sheets were investigated using experimental and numerical methods. Results show that the improvement of contact condition between the dies and sheet suspends the occurrence of micro-cracks and induces more CGP passes. A finer and more homogeneous microstructure is obtained after 6 passes with Teflon layers as lubricant. The ductility of CGP sheets experiences apparent enhancement while the strength gradually decreases. In addition, the uniformity of strain distribution falls with the increase of friction coefficient.

Published: May 2014

The once-through boiler is widely used in high capacity unit currently, however its heat storage capacity is small, and the unit’s response lags during primary frequency regulation. These all lead to the limited frequency regulation ability. For the purpose of studying the primary frequency regulation optimized control strategy, this paper established a primary frequency regulation characteristic simulation platform based on stimulative simulation system. Using this platform, it proposed an improved program for once-through boiler’s primary frequency regulation control strategy. It’s supposed to cover the insufficient heat storage capacity of the boiler by introducing the differential feed forward signal of the fuel supply and water flow. The simulation result shows that the proposed control scheme effectively improves the speed of primary frequency regulation. This platform provides a reliable basis for once-through boiler’s primary frequency regulation control strategy, and also has a certain guiding significance for further study.
