金属切削加工中难加工材料2Cr13的本构模型
Constitutive Model of 2Cr13 for Finite Element Analysis of Chip Formation Process
摘要
Abstract
The prediction accuracy of cutting process simulation is related with the description of nonlinear behavior of material at extremely high strain, strain rate and temperature in machining. An integral Johnson-Cook model was presented herein to characterize the mechanical behavior of work materials in machining, and the parameters in the model were determined by fitting the data from both quasi -static compression and cutting tests. Then the material equation of 2Cr13 stainless steel was derived with this method and used in the finite element model of orthogonal cutting with carbide tools. At last, the simulation results were verified with experimental data.关键词
