该损伤模型通过
商用有限元软件ABAQUS /Explicit 的用户子程序VUMAT 实现，并使用该模型对碳纤维增强环氧树脂
复合材料层合板在横向低速冲击作用下的损伤和变形行为进行预测分析． 数值仿真的结果与试验结
果进行了比较，吻合良好，验证了该模型的有效性．(Through coding user subroutine VUMAT of finite element software ABAQUS /explicit，
and applied the model to an example，carbon fiber reinforced epoxy composite laminates
under low velocity impact，the prediction for damage and deformation were good agreement
with the experimental results．)
