This work is interrested in simulating the local cracking of uranium dioxide during a postulated Reactivity Initiated Accident (RIA). More specifically, the present work addresses the modelling and the simulation of crack initiation and propagation in ductile materials which failed by void nucleation, growth and coalescence. One of the current research frameworks on crack propagation is the use of the cohesive-volumetric approach where the crack growth is modelled as decohesion of two surfaces in a continuum material. In this framework, the material behavior is characterized by two constitutive relations - the volumetric constitutive law relating stress and strain, and a traction-separation law across a two-dimensional surface embedded in ...
