Multiscale Modeling of Carbon Fiber Reinforced Composites with a Local Interface Model

Abstract
This study focuses on how different interface models influence the micro and macro scale properties in epoxy-based composites reinforced with CNT fibers. In order to simulate the material behavior properly, a hierarchical multiscale framework is employed, where the information from all the RVEs in the subscale are passed to the next scale for independent and off-line simulations. Due to the lack of spatial derivatives in its governing equations and therefore advantages of treating singularities, PD theory is used to solve the problem. Previous studies show how the small changes in the interface model have a significant effect on the micro and macro scale results. Here, we propose using a local interface model within the PD framework to allow the interface to be treated with high fidelity.
