Modification of exponential based hyperelastic strain energy to consider free stress initial configuration and Constitutive modeling
In this research, the exponential stretched based hyperelastic strain energy was modified to provide the unstressed initial configuration. To this end, as the first step, the model was calibrated by the experimental data to find the best material parameters. The fitting results indicated material stability in large deformations and basic loading modes. In the second step, the initial pseudo str...
متن کاملA New Technique based on Strain Energy for Correction of Stress-strain Curve
Tensile stress-strain curve is of high importance in mechanics of materials particularly in numerical simulations of material deformations. The curve is usually obtained by experiment but is limited by necking phenomenon. Engineering stress-strain curve is converted to true stress-strain curve through simple formulas. The conversion, however, is correct up the point of necking. From this point ...
متن کاملThermal analysis of functionally graded materials in cylinders and pistons based on super element method
In the present article, the thermal analysis of the cylinder and the piston in four-cylinder engines, made of functionally graded materials (FGMs), has been performed by using the super element method. The objective of using FGMs in the cylinder and the piston is to increase their performance. FGMs include a combination of ceramics and metals. Inside the cylinder, the ceramic is considered and ...
متن کاملChoosing a Commercial Broiler Strain Based on Multicriteria Decision Analysis
With the complexity and amount of information in a wide variety of comparative performance reports in poultry production, making a decision is difficult. This problem is overcomed only when all data can be put into a common unit. For this purpose, five different decision making analysis approaches including Maximin, Equally likely, Weighted average, Ordered weighted averages and Technique for ...
متن کاملCorrecting the stress-strain curve in hot compression test using finite element analysis and Taguchi method
In the hot compression test friction has a detrimental influence on the flow stress through the process and therefore, correcting the deformation curve for real behavior is very important for both researchers and engineers. In this study, a series of compression tests were simulated using Abaqus software. In this study, it has been employed the Taguchi method to design experiments by the factor...
