Deep operator network for surrogate modeling of poroelasticity with random permeability fields
Sangjoon Park, Yeonjong Shin, Jinhyun Choo
Poroelasticity -- coupled fluid flow and elastic deformation in porous media -- often involves spatially variable permeability, especially in subsurface systems. In such cases, sim…
GeoWarp: An automatically differentiable and GPU-accelerated implicit MPM framework for geomechanics based on NVIDIA Warp
Yidong Zhao, Xuan Li, Chenfanfu Jiang +1
The material point method (MPM), a hybrid Lagrangian-Eulerian particle method, is increasingly used to simulate large-deformation and history-dependent behavior of geomaterials. Wh…
A phase-field model for quasi-dynamic rupture nucleation and propagation of in-plane faults
Fan Fei, Md Shumon Mia, Ahmed E. Elbanna +1
Computational modeling of faulting processes is an essential tool for understanding earthquake mechanics but remains challenging due to the structural and material complexities of…
Crack opening calculation in phase-field modeling of fluid-filled fracture: A robust and efficient strain-based method
Fan Fei, Jinhyun Choo
The phase-field method has become popular for the numerical modeling of fluid-filled fractures, thanks to its ability to represent complex fracture geometry without algorithms. How…
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…
