But other subroutines still need the c definition "implicit real*8" since there may be variables that are c not passed to them through the list or common block. c c (4) This is current as of version 5.6 of ABAQUS. c ... ...

黄永刚老师本构模型的中文解释,建议大家详细阅读。做cpfem的同学也可以多交流。本文编写了一份将单晶塑性力学引进ABAQUS 有限元程序的材料用户子程 序,并回顾了单晶弹塑性和粘塑性形变的有限元公式,包含了小变形理论和严格 的有限应变和旋转理论的描述。单晶体非弹性变形源于晶面滑移,在这里假定它 符合施密特法则。滑移系中分解剪切应力和应变之间的各种自身的和潜在的强化 关系在子程序中以选项的方式出现和引入。
