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 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…
Modeling damage and fracture within strain-gradient plasticity
E. Martínez-Pañeda, C. Betegón
In this work, the influence of the plastic size effect on the fracture process of metallic materials is numerically analyzed using the strain-gradient plasticity (SGP) theory estab…
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…
