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…
A multiscale model of friction considering the influence of third-body wear particles
Parissa Sadat Alavi, Guillaume Anciaux, Jean-François Molinari +2
Accurately predicting friction in sliding interfaces that contain third body wear particles is critical for engineering applications such as sliding movement in pistons, bearings,…
A Parallelized 3D Geomechanical Solver for Fluid-induced Fault Slip in Poroelastic Media
Emil Rinatovich Gallyamov, Guillaume Anciaux, Nicolas Richart +2
We present a fully implicit formulation of coupled fluid flow and geomechanics for fluid injection/withdrawal in fractured reservoirs in the context of CO2storage. Utilizing a Gale…
