Abstract
In order to improve the simulation precision of nonlinear materials,focuses on the constants of the Mooney-Rivlin constitutive model for hyperelastic materials,aiming to compare whether the constants obtained from uniaxial tensile and compressive tests are consistent.Firstly,standard tensile and compression splines are made and subjected to uniaxial tensile and uniaxial compression tests to obtain deformation tension or pressure data.Secondly,process the data to obtain the true stress-strain curve.Then input the stress-strain curves obtained from tension or compression into the simulation software for data fitting to obtain the Mooney-Rivlin model constants C10 and C01,and compare the consistency of the two sets of constants.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 results show that the model constants obtained from tensile and compressive tests are inconsistent,and the type of test to be adopted needs to be determined based on the specific stress situation,which provide experimental basis for subsequent material definition and simulation work.关键词
