Title Biaxial tensile test and finite element numerical simulation analysis
Abstract
This paper first do uniaxial tensile experiment to obtain the energetic material’s basic parameter which will be used in biaxial tensile test, and then do the biaxial tensile test and finite element analysis software ANSYS finite element numerical simulation, so that can get the result of material in the experiment and compared with the result of the numerical simulation with finite element software analysis. In the finite element simulation, the stress distribution of specimens is uniform along the center of symmetry in the process of the tensile. With the increase of stretching rate, the strength of the material can withstand extreme value also will increase. Simulation results broadly in line with the actual test results, which shows that the model for simulation of the cruciform material biaxial tensile test has certain reliability and provide reference for simulation of actual biaxial tensile test. 源`自*六)维[论*文'网www.lwfree.cn
