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.

用于分析火灾情景下复合材料的热-流体-机械耦合近场动力学模型

摘要 本研究提出了一种耦合热-流体-机械近场动力学模型来预测火灾情景下的复合响应。三层层压复合材料是通过使用基于普通状态的热机械近场动力学建模的。通过考虑复合材料的热降解特性来模拟机械变形和热传导。通过使用基于近场动力学微分算子的热流体模型，将火模拟为导热流体。ISO温度-时间曲线用于呈现火灾引起的高温。研究了由于直接接触火和由火引起的热气体引起的复合材料损坏。
