Analysis of the influence of microstructural traps on hydrogen assisted fatigue
Rebeca Fernández-Sousa, Covadonga Betegón, Emilio Martínez-Pañeda
We investigate the influence of microstructural traps on hydrogen diffusion and embrittlement in the presence of cyclic loads. A mechanistic, multi-trap model for hydrogen transpor…
The role of plastic strain gradients in the crack growth resistance of metals
Emilio Martínez-Pañeda, Vikram S. Deshpande, Christian F. Niordson +1
Crack advance from short or long pre-cracks is predicted by the progressive failure of a cohesive zone in a strain gradient, elasto-plastic solid. The presence of strain gradients…
Steady-state fracture toughness of elastic-plastic solids: Isotropic versus kinematic hardening
Kristian J. Juul, Emilio Martínez-Pañeda, Kim L. Nielsen +1
The fracture toughness for a mode I/II crack propagating in a ductile material has been subject to numerous investigations. However, the influence of the material hardening law has…
Crack growth resistance in metallic alloys: the role of isotropic versus kinematic hardening
Emilio Martínez-Pañeda, Norman A. Fleck
The sensitivity of crack growth resistance to the choice of isotropic or kinematic hardening is investigated. Monotonic mode I crack advance under small scale yielding conditions i…
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…
