ABAQUS input file and supporting thermochemical data for charring ablation modeling

This dataset contains an ABAQUS input file and supporting thermochemical data used for finite element modeling of charring ablation of phenolic-based ablative materials. The numerical configuration implements a one-dimensional charring ablation material response framework accounting for material decomposition, pyrolysis gas effects, and progressive surface recession. The ABAQUS input file was created and modified to support the present study. Thermogravimetric analysis (TGA) data used for kinetic parameter identification were obtained from previously published literature; no original experimental data are included. The UMATHT user subroutine implementing the material response model is not publicly distributed in order to protect the authors’ intellectual property. The governing equations, assumptions, and numerical implementation details are fully described in the associated journal publication.
