Unified sparse framework for large-scale simulations using the material point method
Yidong Zhao, Lars Blatny, Xiang Feng +3
The material point method (MPM) is a hybrid particle-grid method widely used for large deformation problems with history-dependent behavior, including geophysical mass flows. Stand…
Unstructured Moving Least Squares Material Point Methods: A Stable Kernel Approach With Continuous Gradient Reconstruction on General Unstructured Tessellations
Yadi Cao, Yidong Zhao, Minchen Li +4
The Material Point Method (MPM) is a hybrid Eulerian Lagrangian simulation technique for solid mechanics with significant deformation. Structured background grids are commonly empl…
Circumventing volumetric locking in explicit material point methods: A simple, efficient, and general approach
Yidong Zhao, Chenfanfu Jiang, Jinhyun Choo
The material point method (MPM) is frequently used to simulate large deformations of nearly incompressible materials such as water, rubber, and undrained porous media. However, MPM…
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…
Devices for high precision x-ray beam intensity monitoring on BSRF
LI Hua-Peng, Kun Tang, Yi-Dong Zhao +4
Synchrotron radiation with the characteristic of high brilliance, high level of polarization, high collimation, low emittance and wide tunability in energy has been used as a stand…
