Coupled field modelling of thermomechanical response in materials using peridynamic heat transport model and non-ordinary state-based peridynamics

Predicting the mechanical response of materials subjected to transient heat processes is crucial in various engineering applications. This paper introduces a novel peridynamic (PD) coupled field model formulated within the framework of NonOrdinary State-Based Peridynamics (NOSBPD). This model offers the capability to simulate the coupled thermo-mechanical behaviour of materials by incorporating both thermal transport and mechanical deformation analyses. To verify the model's accuracy, a benchmark problem involving a steel plate undergoing transient thermal expansion is investigated. This model presents a valuable tool for various engineering applications involving coupled thermo-mechanical processes.
