Abstract

Thermo-mechanical analysis of ablative materials is of great importance to Thermal Protection System design. A coupling method for thermo-mechanical and ablation response model is proposed using a Finite Volume approach. This method is capable of simulating both transient and static structural response. The solver is verified using a series of test cases and then fully coupled to a material response code. Coupled results show that the temperature field has a significant effect on mechanical performance and stress generation which can lead to mechanical fracture as well as spallation.
