The semi-explicit nonsmooth Newmark time integrator for robust unilateral contact in dynamic fragmentation simulations
Thibault Ghesquière-Diérickx, Guillaume Anciaux, Vincent Acary +1
Numerical simulations of solids undergoing dynamic fragmentation, a problem characterized by dynamic fracture and dense contacts, require accurately capturing the transition from a…

Stability of Extrinsic Cohesive-Zone Model with Penalty-Based Contact in Explicit Dynamic Fragmentation Simulations
Thibault Ghesquière-Diérickx, Jean-François Molinari, Guillaume Anciaux
Dynamic fragmentation simulations are essential for predicting material response at high strain rates, yet explicit dynamic simulations that combine an extrinsic cohesive-zone mode…
