Abstract
In order to improve the simulation precision of nonlinear materials,focuses on the Mooney-Rivlin model constants,aiming to compare the simulation accuracy obtained by defining nonlinear materials using engineering stress data and real stress data.Firstly,make a standard tensile spline,conduct tensile tests on the spline,and obtain the deformation tension curve of the spline.Secondly,the experimental data was processed to obtain the engineering stress-strain curve and the true stress-strain curve of the rubber.Then input the obtained stress-strain curve into ANSYS for curve fitting,and obtain the two parameter Mooney-Rivlin model constants C10 and C01.Finally,a nonlinear simulation analysis is conducted to compare the stress-strain curve obtained from the simulation with the test results to verify the accuracy of the model.The research results show that the fitting results obtained by using the real stress-strain curve are more in line with the actual situation,can guide the definition and simulation of subsequent nonlinear models.关键词
