FE Modeling of Wear Mechanisms in UD-GFRP Composites Using Single-Indenter Scratch Test: A Micromechanical Approach

摘要

This paper addresses the sensitivity of the elementary wear mechanisms of UD-GFRP composite to the tribological parameters. A scanning electron microscope (SEM) was used to assess the wear mechanisms on the scratched UD-GFRP composite for different test conditions. A 3D FE micromechanical models was developed using ABAQUS/Explicit to simulate single indenter scratch test (SST). Both material behavior and damage of fibers and matrix are described using Johnson Cook behavior law. However, the fiber/matrix interface was modeled using the cohesive zone approach by the mean of the cohesive elements. The numerical results show a good agreement with the experimental wear mechanisms.
