Multiphysics Lattice Discrete Particle Modeling (M-LDPM) for the Simulation of Shale Fracture Permeability
Weixin Li, Xinwei Zhou, J. William Carey +2
A three-dimensional Multiphysics Lattice Discrete Particle Model (M-LDPM) framework is formulated to investigate the fracture permeability behavior of shale. The framework features…
Adaptive Multiscale Homogenization of the Lattice Discrete Particle Model for the Analysis of Damage and Fracture in Concrete
Roozbeh Rezakhani, Xinwei Zhou, Gianluca Cusatis
This paper presents a new adaptive multiscale homogenization scheme for the simulation of damage and fracture in concrete structures. A two-scale homogenization method, coupling me…
Isogeometric implementation of high order microplane model for the simulation of high order elasticity, softening, and localization
Erol Lale, Xinwei Zhou, Gianluca Cusatis
In this paper, a recently developed Higher Order Microplane (HOM) model for softening and localization, is implemented within a isogeometric finite element framework. The HOM model…
A multiscale framework for the simulation of the anisotropic mechanical behavior of shale
Weixin Li, Roozbeh Rezakhani, Congrui Jin +2
Shale, like many other sedimentary rocks, is typically heterogeneous, anisotropic, and is characterized by partial alignment of anisotropic clay minerals and naturally formed beddi…
