Virtual elements on agglomerated finite elements to increase the critical time step in elastodynamic simulations
N. Sukumar, Michael R. Tupek
In this paper, we use the first-order virtual element method (VEM) to investigate the effect of shape quality of polyhedra in the estimation of the critical time step for explicit…
A momentum preserving frictional contact algorithm based on affine particle-in-cell grid transfers
Michael Tupek, Jacob Koester, Matthew Mosby
An efficient and momentum conserving algorithm for enforcing contact between solid bodies is proposed. Previous advances in the material point method (MPM) led to a fast and simple…
A Variational Phase-Field Model For Ductile Fracture with Coalescence Dissipation
Tianchen Hu, Brandon Talamini, Andrew J. Stershic +2
A novel phase-field for ductile fracture model is presented. The model is developed within a consistent variational framework in the context of finite-deformation kinematics. A nov…
A phase-field formulation for dynamic cohesive fracture
Rudy J. M. Geelen, Yingjie Liu, Tianchen Hu +2
We extend a phase-field/gradient damage formulation for cohesive fracture to the dynamic case. The model is characterized by a regularized fracture energy that is linear in the dam…
