Strain Gradient Plasticity-Based Modeling of Damage and Fracture

Gradient-enhanced modeling of crack growth resistance, hydrogen diffusion and environmentally assisted cracking highlighted the relevance of an appropriate characterization of the mechanical response at the small scales involved in crack tip deformation.

Modelarea cu gradient a rezistentei la cresterea fisurilor, difuzia hidrogenului si fisurarea asistata de mediu au evidentiat relevanta unei caracterizari adecvate a raspunsului mecanic la scarile mici implicate in deformarea varfului fisurilor.
