Abstract

The utilization of composite materials in aerospace industry is consistently increasing. One area which requires attention is the modeling of mechanical and/or thermal shock loading on composite structures. Such a phenomenon can be expressed within a fully coupled framework where both the mechanical and thermal fields may have an effect on each other. Furthermore, if damage initiation and propagation predictive capability is also required, the complexity of the analysis increases significantly. Performing such an analysis by using traditional techniques is challenging if not impossible. However, a new continuum mechanics formulation, peridynamics, can overcome such difficulties due to its natural suitability for failure modeling in an intrinsic manner. The peridynamics is a nonlocal continuum theory which allows governing field equations to be applicable at discontinuities. This applicability at discontinuities is achieved by replacing the spatial derivatives, which lose meaning at discontinuities, with integrals that are valid regardless of the existence of a discontinuity. Furthermore, its multi-physics capability makes it a unique approach for fully coupled analysis of different fields. This study presents a fully coupled peridynamic thermomechanical analysis of fiber-reinforced composites.
