Predictive numerical modelling of the transition from continuum to discontinuum in solid bodies subjected to loading is becoming extremely imporl the streamlining in engineering design reaches towards the ultimate limits of material-carrying capacity. Nowhere is this more important than in situations of extreme loading caused by explosions or collisions in which the safety aspect is imperative. In situations of continued deformation, fe processes complete with cracking, fracture and separation along the created contact interfaces, resulting in loss of structural integrity. The solutio methods employed by currently available commercial software regularly fail to deliver accurate predictions of failure processes. The aim of the proposed research is to improve the predictive modelling of fast fracture in toughened and glass. We shall use recent ideas from the mathematical theory of posteriori error estimation to derive sharp bounds on the error in quantities of engineering interest. These bounds will then be implemented into an adaptive mesh refinement algorithm. We shall also perform computational multiscale modelling by combining a finite element method with a discrete element method based on particle assemblies for the coputational modelling of the mirror-mist-and-hackle phenomenon.
