【求助】Johnson-cook模型参数及板料回弹求助
|
|||
|
求SUS304不锈钢的johnson-cook模型参数。即A、B、n、C……分别是多少?最好有文献依据,我QQ306847490,谢谢! 附注:SUS304不锈钢相当于国产的0Cr18Ni9不锈钢。 我在Explicit中用Johnson-Cook模型分析板料的冲击成形,然后在Standard中模拟回弹,但提示Standard无Johnson-Cook模型,警告如下,请问对回弹有影响吗,应该怎么解决,谢谢! MATERIAL MATERIAL-1 INCLUDE THE JOHNSON-COOK PLASTICITY MODEL. THIS MODEL IS NOT AVAILABLE IN Abaqus/Standard. STATE VARIABLE ASSOCIATED WITH THIS MODEL WILL NOT BE IMPORTED AND WILL NOT BE AVAILABLE IN SUBSEQUENT ANALYSES The previous analysis uses the johnson-cook plasticity material model. Currently state variables are transferred only for linear elastic, hyperelastic, mullins effect, hyperfoam, time domain viscoelasticity, mises plastic, kinematic and combined hardening, and user defined material models when the state=yes on the *import option. Material/behavior material-1 has been redefined in the current analysis. Care must be taken to ensure that a consistent state can be maintained during the import procedure. One or more materials defined in the previous analysis is not supported for import. This may be because a material defined in the previous analysis is not available in the current analysis product. The import of such materials may result in other errors unless the material was associated with elements that are not being imported. |
