A cohesive zone framework for environmentally assisted fatigue
Susana del Busto, Covadonga Betegón, Emilio Martínez-Pañeda
We present a compelling finite element framework to model hydrogen assisted fatigue by means of a hydrogen- and cycle-dependent cohesive zone formulation. The model builds upon: (i…
Strain gradient plasticity-based modeling of hydrogen environment assisted cracking
Emilio Martínez-Pañeda, Christian F. Niordson, Richard P. Gangloff
Finite element analysis of stress about a blunt crack tip, emphasizing finite strain and phenomenological and mechanism-based strain gradient plasticity (SGP) formulations, is inte…
A finite element framework for distortion gradient plasticity with applications to bending of thin foils
Emilio Martínez-Pañeda, Christian F. Niordson, Lorenzo Bardella
A novel general purpose Finite Element framework is presented to study small-scale metal plasticity. A distinct feature of the adopted distortion gradient plasticity formulation, w…
Strain gradient plasticity modeling of hydrogen diffusion to the crack tip
Emilio Martínez-Pañeda, Susana del Busto, Christian F. Niordson +1
In this work hydrogen diffusion towards the fracture process zone is examined accounting for local hardening due to geometrically necessary dislocations (GNDs) by means of strain g…
On fracture in finite strain gradient plasticity
Emilio Martínez-Pañeda, Christian F. Niordson
In this work a general framework for damage and fracture assessment including the effect of strain gradients is provided. Both mechanism-based and phenomenological strain gradient…
Non-local plasticity effects on notch fracture mechanics
Emilio Martínez-Pañeda, Susana del Busto, Covadonga Betegón
We investigate the influence of gradient-enhanced dislocation hardening on the mechanics of notch-induced failure. The role of geometrically necessary dislocations (GNDs) in enhanc…
