不同变形条件下锰铜合金的应力松弛特性及数值仿真
Stress Relaxation Characteristics and Numerical Simulation of Mn-Cu Alloy under Different Deformation Conditions
摘要
Abstract
The improvement of computing power provides a support for finite element simulation analysis,which can solve more complex structures and nonlinear problems more efficiently.In this study,based on the finite element simulation analysis technology,the complex mechanical properties of Mn-Cu alloy are simulated.Prony series con-stitutive model and parallel rheological constitutive model are respectively adopted to simulate the stress relaxation test of Mn-Cu alloy under different deformation conditions.The stress relaxation experimental data are extracted and converted into the corresponding model parameters and the finite element simulation calculation is carried out.The simulation model parameters which can accurately describe the nonlinear mechanical properties of Mn-Cu alloy are obtained.By comparing the simulation and experimental results,it is concluded that the parallel rheological frame-work can more accurately characterize the stress relaxation behavior of Mn-Cu alloy.Under different initial strain conditions,the relative error of the simulation results and the test results under corresponding working conditions is less than 1%.Compared with Prony series constitutive model,parallel rheological framework is more suitable for the simulation of Mn-Cu alloy under complex working conditions.关键词
