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…
Convergent Graph Solvers
Junyoung Park, Jinhyun Choo, Jinkyoo Park
We propose the convergent graph solver (CGS), a deep learning method that learns iterative mappings to predict the properties of a graph system at its stationary state (fixed point…
Phase-field modeling of rock fractures with roughness
Fan Fei, Jinhyun Choo, Chong Liu +1
Phase-field modeling -- a continuous approach to discontinuities -- is gaining popularity for simulating rock fractures due to its ability to handle complex, discontinuous geometry…
