can be used in conjunction with user subroutine USDFLD to redefine any field variables before they are passed in.
通过定义STATEV:
This array will be passed in containing the values of these variables at the start of the increment unless they are updated in user subroutine USDFLD or UEXPAN, in which case the updated values are passed in.
刚查了下creep可以调用USDFLD:
通过定义STATEV:
This array will be passed in containing the values of these variables at the start of the increment unless they are updated in user subroutine USDFLD or UEXPAN, in which case the updated values are passed in.
所以，理论上来讲，你可以先在USDFLD里面获得最大主应力（GETVARM）,然后再传到STATEV里面,最后在CREEP里面调用STATEV.
