A Dislocation-Based Constitutive Model for Hydrogen-Deformation Interactions and a Study of Hydrogen-Induced Intergranular Fracture
This thesis presents two models of the effect of hydrogen on materials. Both models are intended to link experimental observations of material microstructure with macroscopically observable results. The first model creates a continuum, rate dependent plasticity model that incorporates the effect of …

Hydrogen effects on the evolution of plastic deformation in polycrystalline nickel: A mechanism for intergranular failure
Hydrogen embrittlement is a significant and pervasive phenomenon in many structural metals applications, but the underlying physical mechanism is not yet fully understood. The mechanism for hydrogen-induced intergranular failure of polycrystalline nickel was investigated in a series of uniaxial …

Steady crack growth through ductile metals: Computational studies
… analyses focus on steady crack growth within a hydrogen-charged material to explore primary features of the streamline integration methodology while providing new results relevant to hydrogen embrittlement at engineering scales. Ductile crack propagation occurs through a homogeneous, high …
