Abstract
In this research we use uncoupled analysis to evaluate the impact resistance of multi-layer coatings. We conduct high strain-rate simulation by ANSYS. Then the results of stress and strain are in put to damage analysis program which employs the elasto-viscoplastic damage constitutive equation based on continuum damage mechanics. Both of tensile fracture analysis and drop impact analysis have almost agreed well with the corresponding experimental results. Uncoupled analysis for dynamic damage mechanics problems can be expected to be used as a computational tool for the evaluation and the design of multi-layer coatings.
