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 ...

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 ...

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 ...

Dynamic fragmentation of a ring: Predictable fragment mass distributions

Anthony Christopher Davison, Irene Vicari, Jean-François Molinari, Sarah Levy

We employ a finite element framework, coupled to cohesive elements, to model material decohesion of a uniformly expanding ring. Our study focuses on the average fragment mass, the distribution of fragment masses, and the heaviest fragments. The computed fr ...

Exploring the Physics behind Dynamic Fragmentation through Parallel Simulations

Sarah Levy

The physical mechanisms underlying the dynamic fragmentation of heterogeneous brittle materials are explored through numerical simulations. The use of computational facilities, rather than experimental or fundamental sciences, ensures the accurate tracking ...
