说明：  黄永刚所编写的晶体本构子程序。将单晶塑性力学引进 ABAQUS 有限元程序的材料用户子程序， 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
(The crystal constitutive subroutine written by Huang Yonggang. The single-crystal plastic mechanics was introduced into the material user subroutine of the ABAQUS finite element program, which included the description of the small deformation theory and the strict finite strain and rotation theory. The inelastic deformation of a single crystal originates from the crystal plane slip, where it is assumed to conform to Schmitt's law. The various self- and potential reinforcement relationships between the shear stress and the strain in the slip system appear and are introduced as options in the subroutine)
