G0310301 Damage Analysis of Sprayed Coatings by Locally-Coupled Approach

Abstract

The stress-strain curves for carbide cermets which are typical sprayed coatings have been identifled by using the elasto-viscoplastic damage constitutive equation with twelve material constants based on continuum damage mechanics. Locally-coupled approach has been applied to the elasto-viscoplastic damage analysis of a beam with sprayed coating under three-point bending to show the validity of the present material and computational modeling.
