Multiscale Modeling of Composites

PROJECT TITLE:
EFFECT OF INTERFACE DEBONDING ON CONSTITUTIVE RESPONSE OF PARTICULATE AND FIBER COMPOSITES

PARTICIPANTS: JAY PATEL (MS), HELEN HINGLIS (PHD – NOW AT THE U. OF PRETORIA), PROF. KAREL MATOUS (U. NOTRE DAME) PROF. HENRI TAN (U. MANCHESTER) AND PROF. PHILIPPE GEUBELLE

SUPPORT: DOE/ASC CENTER FOR THE SIMULATION OF ADVANCED ROCKETS

Picture 2PROJECT DESCRIPTION: In this project, we use multiscale finite element modeling techniques and micromechanics-based homogenization schemes to investigate the effect of inclusion/matrix debonding on the macroscopic response of particulate and fiber-reinforced composites.
