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

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

Additional information: For more information on the micromechanics-based approach, see this document.
