This paper deals with experimental and finite element analysis of the stretch flanging process using AA- 5052 sheets of 0.5 mm thick. A parametrical study has been done through finite element simulation to inspect the influence of procedural parametrical properties on maximum thinning (%) within the stretch flanging process. The influence of preliminary flange length of sheet metal blank, punch die clearance, and width was examined on the maximum thinning (%). An explicit dynamic finite element method was utilized using the finite element commercial package ABAQUS. Strain measurement was done after conducting stretch flanging tests. A Mesh convergence examination was carried out to ascertain the maximum percentage accuracy in FEM model. It is found through finite element simulation that the width of sheet metal blanks has a greater impact on the maximum percentage of thinning as compared to preliminary flange length, and clearance of the punch dies.

AbstractThe problem considered in this work is the development of simulation method for simulating car crash which utilizes simple car—impact attenuator model developed in MATLAB. Usually, car crash simulation is done using full finite element simulation which could take hours or days depending on the model size. The purpose of proposed method is to achieve quick results on the car crash simulation. Past works which utilizes simple car—impact attenuator model to simulate car crash use continuous time model and the impact attenuator parameter is obtained from the experimental results. Different from the related works, this work uses discrete time model, and the impact attenuator parameter is obtained from finite element simulation. Therefore, the proposed simulation method is not only achieving quick simulation results but also minimizing the cost and time in obtaining the impact attenuator parameter. The proposed method is suitable for parametric study of impact attenuator.

Stress Levels

Abstract The mechanical behavior of materials plays a vital role in the structural performance of designed structures. Therefore, significant resources are devoted globally towards experimental characterization of material behavior, especially for the experiments requiring particular protocols. Contrary, finite element analysis tools have made a substantial contribution to the design of structural elements, which could conserve a significant amount of resources and material wastage. Evaluation of fatigue life of materials is necessary to predict the life expectancy of the structures precisely, and opening stress levels under fatigue loading contributes towards this evaluation. Railways serve as freight and passenger carrier transportation modes. The railway axles contribute as the primary load-carrying element; therefore, the design of railway axles and the study of their mechanical behavior under repeated loading is vital. In this study, the authors present a finite element simulation technique to evaluate the opening stress levels for two structural steels subjected to low cycle fatigue. The finite element analysis (FEA) model was designed and validated following the simulation of fatigue crack propagation under high plasticity conditions. Numerical simulation results were compared with the experimental results obtained earlier through the digital image correlation (DIC) technique. To conclude, FEA could be a useful tool to predict crack closure phenomena and, ultimately, the fatigue life of components. However, researchers need to establish more sophisticated numerical tools for more precise results in case of high plasticity conditions near the crack tip.

Based on the study of the effect of parametric variation of quartz flexible accelerometer in storage condition, the varying mechanism and causes of bias and scale factor varying were analyzed. According to the analysis results of mechanism, the parts of finite element modeling and the parameters-input forms were determined. Considering the varying magnetic properties of permanent magnetic material impacted on the accelerometer, an approach of loading the servo-circuit formulas and modeling the quartz flexible accelerometer in ANSYS finite element analysis (FEA) software was given, and the algorithm process of FEA coupled magneto-structural simulation was also given. Finally, one certain accelerometer was simulated by FEA software, and a temperature testing was made.

ABSTRACTNanoindentation experiments are now widely used to study the elastic and plastic properties of thin films. Simulation of these experiments has been performed using finite element analysis. Results show the large influence that pile-up or sink-in behavior have on hardness calculations. Results also show that a compliant substrate significantly affects the measured hardness of a stiffer coating. The measured hardness of a compliant coating is less effected by a stiffer substrate.

Bolted Flange

JIS B 2251 (former HPIS Z 103 TR) is published as the assembly guidelines for bolted flanged joints with ring-type gasket, which employs the rotational clockwise tightening sequence in the main tightening step. Actual flanged joints have misalignment, and when the flanged joints are assembled, the bending moment to modify the influence of the misalignment acts on the flange faces. There is risk that the uniformity of gasket stress distribution is affected by the bending moment of the misalignment. So, the influence of the misalignment on the uniformity of the gasket stress distribution is investigated using finite element analysis. Consequently, setting the acceptance criteria of the misalignment to get the uniformity of gasket stress distribution. The influence of the uniformity of the gasket stress distribution in case of changing the starting tightening bolt against the direction of the misalignment is also investigated.
