This study presents a 3D peridynamic (PD) model to simulate the pyrolysis process and crack propagation of charring materials due to aerodynamic heating. The model is based on the coupled solution of the nonlinear thermal conduction with surface recession and equation of motion considering thermal expansion due to heat and shrinkage strain due to mass loss. The accuracy of the model with and without surface recession is verified by simulating the pyrolysis of charring materials H41N and AVCOAT 5026, respectively. The PD temperature predictions recover the available experimental and simulation results. In addition, this approach successfully captures the shrinkage deformation and crack propagation of charring material during ablation.
