Strain Gradient Plasticity-Based Modeling of Damage and Fracture

Nominated as an outstanding PhD thesis by University of Oviedo, Spain

Is the first book to address the modeling of size effects in metal plasticity

Proposes a general framework for crack tip assessment accounting for the role of geometrically necessary dislocations (GNDs) in fracture and damage
