Modeling Heat Conduction in Composite Materials Using a Nonlocal Lattice Particle Method

Abstract

In this paper, the heat conduction in composite materials is studied using a recently developed nonlocal lattice particle model. Specifically, we investigate the heat conduction in cross-ply laminated composite and short fiber reinforced composite. For the laminate composite, the lattice rotation scheme is employed to model the ply orientation and account for anisotropic thermal conductivity. For short fiber reinforced composite, each phase is assumed to be isotropic but with distinct thermal conductivities. Good agreement is found between the model predictions and finite element results.
