... activity. In this work, we use a coupled diffusion-crystal plasticity model to incorporate hydrogen transport associated with dislocation sweeping and pipe diffusion in addition to standard lattice diffusion. Moreover, we consider generation of vacancies via plastic deformation and stabilization...

... of mechanical stress on oxygen diffusion, a sequentially coupled deformation-diffusion analysis was carried out for a generic specimen geometry under creep loading condition using a submodeling technique. The material constitutive behavior was described by a crystal plasticity model at the grain level...

..., simulations carried out by Baczynski and Jonas ( 4 ) based on the rate-sensitive theory of crystal plasticity predicted a persistence of the D2 orientation in negative shear, but only under lengthening conditions. However, Oliveira and Montheillet ( 5 6 ) did not observe the same behavior for fixed-end...

...Kaan Inal; Hari M. Simha; Raja K. Mishra A new finite element analysis based on rate dependent crystal plasticity theory has been developed to investigate the effects of second-phase particles on the initiation and propagation of localized deformation in the form of shear bands. The new model can...
