cohesive如何模拟达到判定准则即失去粘结作用?

用了surface-based cohesive behaviour作为面和面的接触性质,想模拟一旦达到判定准则就失去粘结作用,不需要损伤退化的过程,如何实施?不设置damage evolution的参数可以吗?
下面是帮助手册里面的解释,意思是不设置damage evolution就不会发生损伤,粘结不会破坏吗?
“If the damage initiation criterion is specified without a corresponding damage evolution model, Abaqus evaluates the damage initiation criterion for output purposes only; there is no effect on the response of the cohesive surfaces (i.e., no damage will occur). Cohesive surfaces do not undergo damage under pure compression.”
