A variational multiscale immersed meshfree method for heterogeneous materials
Autor: Jacob Koester, Frank Beckwith, H. Eliot Fang, Jiun-Shyan Chen, Tsung-Hui Huang, Michael R. Tupek
Publikováno v: Computational Mechanics. 67:1059-1097
We introduce an immersed meshfree formulation for modeling heterogeneous materials with flexible non-body-fitted discretizations, approximations, and quadrature rules. The interfacial compatibility condition is imposed by a volumetric constraint, whi

A MUSCL-SCNI approach for meshfree modeling of shock waves in fluids
Autor: Jiun-Shyan Chen, Michael J. Roth, Jesse A. Sherburn, Haoyan Wei, Eliot Fang, Michael R. Tupek, Tsung-Hui Huang, Joseph E. Bishop
Publikováno v: Computational Particle Mechanics. 7:329-350
A stable and nodally integrated meshfree formulation for modeling shock waves in fluids is developed. The reproducing kernel approximation is employed to discretize the conservation equations for compressible flow, and a flux vector splitting approac

Treatment of near-incompressibility in meshfree and immersed-particle methods
Autor: Jiun-Shyan Chen, Yuri Bazilevs, Jacob Koester, Georgios Moutsanidis, Michael R. Tupek
Publikováno v: Computational Particle Mechanics. 7:309-327
We propose new projection methods for treating near-incompressibility in small and large deformation elasticity and plasticity within the framework of particle and meshfree methods. Using the $$\overline{\mathbf {B}}$$ and $$\overline{\mathbf {F}}$$

A Variational Phase-Field Model For Ductile Fracture with Coalescence Dissipation
Autor: Brandon Talamini, Tianchen Hu, Andrew J. Stershic, John E. Dolbow, Michael R. Tupek
A novel phase-field model for ductile fracture is presented. The model is developed within a consistent variational framework in the context of finite-deformation kinematics. A novel coalescence dissipation introduces a new coupling mechanism between

Virtual elements on agglomerated finite elements to increase the critical time step in elastodynamic simulations
Autor: 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 three-dimensional elastodynamic finite element (FE) simulations. Low-q
