This paper presents finite element analysis for the lamination-type cracked ceramic coatings subjecting to a tensile loading. The analysis was conducted using the program including the nonlinear elastic constitutive equation for ceramic thermal barrier coatings that was proposed by author. The numerical results for stress field showed that stress singularity field can be characterized by HRR field. The results for damage field revealed that micro crack formed near tip of the crack, and relaxed the tip stress in the inner region of HRR field.
