Influence of internal impacts between fragments in dynamic brittle tensile fragmentation

Dynamic fragmentation phenomena involve two important mechanisms: atomic debonding and internal impacts among formed fragments. While the former, i.e. energy dissipation due to crack propagation, has been frequently studied both theoretically and numerical ...

2D to 3D dynamic fragmentation with parallel cohesive elements

Jean-François Molinari, Nicolas Richart, Marco Vocialta

Dynamic fragmentation is a fast and catastrophic failure that takes place when an extreme load is applied to a material. During this process complex crack patterns develop. Cracks initiate at internal micro-defects, they propagate, eventually branch, and f ...

Fragmentation et Mobilité Urbaine

Yafiza Zorro Maldonado

L’espace public comme beaucoup l’ont saisi, n’est pas simplement composé de trottoirs, parcs et places. Les différents types d’infrastructures de transport urbains et les dynamiques sociales qui s’y produisent en font aussi partie. D’où l’importance de com ...

Data Exchange Problem with Helpers

Michael Christoph Gastpar, Sameer Pawar

In this paper we construct a deterministic polyno- mial time algorithm for the problem where a set of users is interested in gaining access to a common file, but where each has only partial knowledge of the file. We further assume the existence of another ...

Heteroatom Nucleophile Induced C-C Fragmentations to Access Functionalized Allenes

Nicolai Cramer, Tanguy Jean Daniel Saget

The rich structural and reactivity profile of allenes render them versatile synthetic intermediates. However, application of allenes in organic chemistry is often attenuated by inconvenient methods of preparation. Herein we present an operationally simple ...

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 ...
