CRACK TIP MECHANICS WITHIN STRAIN GRADIENT PLASTICITY

Posted on by EmilioMtnez

Continuum crack tip characterization accounting for the local hardening promoted by plastic strain gradients. Development of finite element frameworks to investigate the role of geometrically necessary dislocations under finite strains and rotations. Quantification of the magnitude of stress elevation predicted from mechanism-based and phenomenological strain gradient plasticity theories with respect to conventional plasticity. Assessment of the implications of the plastic size effect in the modelization of several damage mechanisms.
