A new 2D continuous-discontinuous heat conduction model for modeling heat transfer and thermal cracking in quasi-brittle materials

This paper proposes a new 2D continuous-discontinuous heat conduction model to simulate heat transfer and thermal cracking in fractured quasi-brittle materials by combining with mechanical calculations of the Finite-Discrete Element Method. By updating the sharing relationship of the nodes at the cracks, the model can accurately predict the temperature evolution, crack propagation and considers the effect of cracking on heat conduction.
