Modeling irregular boundaries using isoparametric elements in the Material Point Method
Ezra Y. S. Tjung, Shyamini Kularathna, Krishna Kumar +1
The Material Point Method (MPM) is a hybrid Eulerian-Lagrangian approach capable of simulating large deformation problems of history-dependent materials. While the MPM can represen…
Scalable and modular material point method for large-scale simulations
Krishna Kumar, Jeffrey Salmond, Shyamini Kularathna +4
In this paper, we describe a new scalable and modular material point method (MPM) code developed for solving large-scale problems in continuum mechanics. The MPM is a hybrid Euleri…
Mechanics of granular column collapse in fluid at varying slope angles
Krishna Kumar, Jean-Yves Delenne, Kenichi Soga
This paper investigates the effect of initial volume fraction on the runout characteristics of collapse of granular columns on slopes in fluid. Two-dimensional sub-grain scale nume…
