For the development of a computational tool to evaluate the impact resistance of multi-layer coatings, the authors have conducted the finite element formulation for the dynamic damage analysis of multi-layer coatings by using the elasto-viscoplastic damage constitutive equation based on continuum damage mechanics. The proposed method has been applied to the analysis of multi-layer coatings under transverse impact using the material constants determined by the material test results for each coating layer. The identified constitutive modeling and the calculated damage zones under lateral impact have almost agreed well with the corresponding experimental results, although separation of the damaged and fractured zone from the tested specimens has not yet completely simulated because of the use of relatively coarse mesh.
