The Effect of Initial Void on the Elasto-Plastic Properties of Particle-Reinforced Composite Coating

Abstract:

Many defects such as micro-voids, micro-cracks are introduced during the preparation of particle reinforced composite coating, which significantly change the mechanical properties of the coating. Based on Mori-Tanaka’s concept of average stress in the matrix and Eshelby’s equivalent inclusions microscopic theory, an incremental theory coupled with ABAQUS subroutine UMAT, is developed to study the influence of initial void and void growth on elasto-plastic properties of composite coating. In the composite containing hard spherical particles, debonding of particle-matrix interface is a significant damage process, and the effect of initial void on particle damage is also considered.
