Dynamic fragmentation of a brittle plate under biaxial loading: strength or toughness controlled?

Jean-François Molinari, Sarah Levy, Raul Radovitzky

The fragmentation of a brittle plate subjected to dynamic biaxial loading is investigated via numerical simulations. The aim is to extend our understanding of the dynamic processes affecting fragment size distributions. A scalable computational framework b ...

Dynamic fragmentation of ceramics, signature of defects and scaling of fragment sizes

Jean-François Molinari, Sarah Levy

Defects play a critical role in the dynamic fragmentation process of structural ceramics. Cracks initiate at seemingly random locations, propagate and coalesce to form fragments. The process is accompanied by stress release waves, whose influence is diffic ...

How the obscuration-zone hypothesis affects fragmentation: Illustration with the cohesive-element method

Jean-François Molinari, Sarah Levy

The problem of fragmentation prediction is at the origin of various analytical models. Among them, we focus on the ones introducing the idea of obscured zones. They assume that when a crack initiates at a defect, a stress release wave propagates away from ...
