Heat Conduction and Cracking of Functionally Graded Materials Using an FDEM-Based Thermo-Mechanical Coupling Model

In this paper, the steady-state and transient heat transfer processes of functionally graded materials (FGMs) are analyzed using a coupled thermo-mechanical model in GPU parallel multiphysics finite–discrete element software, namely MultiFracS. First, to handle problem heterogeneous is verified. Then, advantages disadvantages FGMs composite response thermal shock loads compared results indicate that can overcome extreme environments better than materials. Finally, influence geometric distribution characteristics double-edge cracks gradient material plate on crack propagation analyzed. The simulation show interaction between affects path under load. inclination angle spacing greatly propagation. Specifically, larger lead smaller angle. approach paper provides new quantitative tool for investigating thermal, elastic, cracking
