Material-agnostic Generalized TMF Damage - Fatigue failure is widespread in many engineering applications • E.g. structures with simultaneous cyclic thermal and structural loading - Need for material-agnostic regularized damage model • Damage materials lead to strain softening behavior: use regularization • Pervasiveness of fatigue failure in different industries: many different materials • Gradient regularized damage greatly improved solution robustness - TMF damage model can be applied to most native Ansys nonlinear materials • Formulate based on incremental inelasticity • Damage driven by inelasticity • Applicable to bilinear and multilinear isotropic/kinematic hardening, rate-dependent Chaboche (viscoplasticity), Drucker-Prager materials - TMF damage can be directly coupled with thermal and pore fluid diffusion - Pore fluid diffusion is based on Darcy Law 164 - TMF damage model - 3 fields coupled (structure, thermal and damage) - 20 cycles of load Damage evolution
