abaqus 的umat计算单层复合材料层合板刚度折减和损伤演化-abaqus of umat calculate single composite laminates stiffness reduction and damage evolution

ABAQUS渐近损伤 用于分析层合板渐近损伤 包含刚度折减-progresive damage

关于复合材料刚度折减，以及损伤演化的用户子程序。程序程序程序程序程序(The commercial FEM software ABAQUS has both powerful capacity for numerically solving varied large-scale nonlinear problems in engineering practice and user-friendly possibility for extending material libraries to

ABAQUS显式子程序用来计算材料是否破坏和对应刚度折减。(ABAQUE/Explicit subroutine vumat)

介绍微观刚度损伤，当大于损伤准则，力学性能发生刚度折减(The micro stiffness damage is introduced. When it is greater than the damage criterion, the stiffness reduction occurs in the mechanical properties)
