A mechanism-based gradient damage model for metallic fracture
S. S. Shishvan, S. Assadpour-asl, E. Martínez-Pañeda
A new gradient-based formulation for predicting fracture in elastic-plastic solids is presented. Damage is captured by means of a phase field model that considers both the elastic…
A mechanism-based multi-trap phase field model for hydrogen assisted fracture
M. Isfandbod, E. Martínez-Pañeda
We present a new mechanistic, phase field-based formulation for predicting hydrogen embrittlement. The multi-physics model developed incorporates, for the first time, a Taylor-base…
A simple and robust Abaqus implementation of the phase field fracture method
Yousef Navidtehrani, Covadonga Betegón, Emilio Martínez-Pañeda
The phase field fracture method is attracting significant interest. Phase field approaches have enabled predicting - on arbitrary geometries and dimensions - complex fracture pheno…
A unified Abaqus implementation of the phase field fracture method using only a user material subroutine
Yousef Navidtehrani, Covadonga Betegón, Emilio Martínez-Pañeda
We present a simple and robust implementation of the phase field fracture method in Abaqus. Unlike previous works, only a user material (UMAT) subroutine is used. This is achieved…
