Abstract

This study presents a coupled thermo-fluid-mechanical peridynamic model to predict composite responses under fire scenarios. Three-layer laminated composite is modelled by using ordinary state-based thermo-mechanical peridynamics. Both the mechanical deformation and the heat conduction are simulated by considering thermal degradation properties of composites. The fire is simulated as a heat-conducting fluid by using a thermo-fluid model based on the peridynamic differential operator. The ISO temperature-time curve is utilized to present the fire-induced high temperature. The composite damages due to direct contact with fire and due to hot gas induced by fire are investigated.
