中文摘要：

多重表面裂缝和界面的分层是在电影 / 底层系统的主要失败机制。在到表面快克的界面的分层伴随物的失败机制之上的夹层的效果被探索。有限元素模型被开发获得压力和精力版本率(犯错) ，它管理接口裂缝的繁殖。在几何学和夹层的组成的性质之上的分层的依赖被检验。结果显示稳定的状态上的夹层的有弹性的模量的效果犯错是不足道的。在不同几何参数的情况下，然而稳定犯错有夹层厚度的增加的减少。这些调查结果导致夹层限制在 ERR 上并且这样有重要效果的结论涂层生活，它能被采用修改陶器的最高的上衣。

英文摘要：

Multiple surface cracks and interfacial delamination are the major failure mechanisms in film/substrate systems.The effect of interlayer upon the failure mechanisms of interfacial delamination concomitant to surface crack was explored.Finite element model was developed to obtain the stress and energy release rate（ERR）,which governs the propagation of interface cracks.The dependences of delamination upon the geometry and constitutive properties of interlayer were examined.The results indicate that the effect of elastic modulus of interlayer on the steady state ERR is insignificant.In cases of different geometrical parameters,however,the steady ERR decreases with the increase of the interlayer thickness.These findings lead to the conclusion that the interlayer constraint has significant effect on the ERR and thus coating life,which can be adopted to modify the ceramic top coat.
