Abstract
In this research we use locally-coupled analysis to evaluate the damage and fracture behaviors of sprayed coatings. We conduct analysis without damage at first (in this case we use ANSYS). Then the results of strain will be input in the damage analysis program which uses the elasto-viscoplastic damage constitutive equation based on continuum damage mechanics. Both of the timing of damage occurrence and the relations of load-displacement have almost agreed well with the three-point bending experimental results. The locally-coupled analysis employing damage mechanics models can be expected to be used as a computational tool for the evaluation and the design of sprayed coatings.
