An Overlapping Schwarz Space-Time Refinement Framework for Material Point Method
Zhaofeng Luo, Minchen Li, Yupeng Jiang
We propose an overlapping Schwarz space-time refinement framework for the material point method (OS-MPM) to improve computational efficiency in problems with strongly localized def…
An Implicit Compact-Kernel Material Point Method for Computational Solid Mechanics
Qirui Fu, Yupeng Jiang, Minchen Li
The numerical performance of the material point method (MPM) is strongly governed by the particle-grid kernel, which controls the trade-off among smoothness, locality, numerical di…
Hybrid continuum-discrete simulation of granular impact dynamics
Yupeng Jiang, Yidong Zhao, Clarence E. Choi +1
Granular impact -- the dynamic intrusion of solid objects into granular media -- is widespread across scientific and engineering applications including geotechnics. Existing approa…
A barrier method for frictional contact on embedded interfaces
Yidong Zhao, Jinhyun Choo, Yupeng Jiang +3
We present a barrier method for treating frictional contact on interfaces embedded in finite elements. The barrier treatment has several attractive features, including: (i) it does…
A Simulation Method for Particle Fragmentation Based on Energy Landscape
Yupeng Jiang, Fernando Alonso-Marroquin, Hans J Herrmann +1
We propose a method for the simulation of particle fragmentation based on the calculation of the energy landscape inside the particle. The landscape of strain energy is calculated…
A hybrid material-point spheropolygon-element method for solid and granular material interaction
Yupeng Jiang, Minchen Li, Chenfanfu Jiang +1
Capturing the interaction between objects that have an extreme difference in Young s modulus or geometrical scale is a highly challenging topic for numerical simulation. One of the…
A Boundary-Spheropolygon Element Method for Stress Determination and Breakage Modelling of Particles
Yupeng Jiang, Hans J. Herrmann, Fernando Alonso-Marroquin
We present a boundary-spheropolygon element method (BSEM), that combines the boundary integral method (BIM) and the spheropolygon-based discrete element method (SEM). The interacti…
