Journal ArticleDOI
Coupled phase-field and plasticity modeling of geological materials: From brittle fracture to ductile flow
TL;DR: In this paper, the authors derive a phase-field formulation for fracture in elastic-plastic materials as a balance law of microforce, in a new way that honors the dissipative nature of the fracturing processes.
Journal ArticleDOI
Stabilized mixed finite elements for deformable porous media with double porosity
Jinhyun Choo,Ronaldo I. Borja +1 more
TL;DR: In this article, a finite element framework for coupled solid deformation and fluid diffusion in double porosity media was developed, which employs a thermodynamically consistent effective stress, and mixed finite elements that interpolate the solid displacement and pore pressures in the macropores and micropores were used for this purpose.
Journal ArticleDOI
Hydromechanical Modeling of Unsaturated Flow in Double Porosity Media
TL;DR: In this article, a thermodynamically consistent framework for hydromechanical modeling of unsaturated flow in double-porosity media is developed, where conservation laws are formulated incorporating an effective stress tensor that is energy-conjugate to the rate of deformation tensor of the solid matrix.
Journal ArticleDOI
Cracking and damage from crystallization in pores: Coupled chemo-hydro-mechanics and phase-field modeling
TL;DR: In this paper, a theoretical and computational framework for modeling these crystallization-induced deformation and fracture in fluid-infiltrated porous materials was developed, where conservation laws were formulated for coupled chemo-hydro-mechanical processes in a multiphase material composed of the solid matrix, liquid solution, gas, and crystals.
Journal ArticleDOI
Determination of air-void parameters of hardened cement-based materials using X-ray computed tomography
TL;DR: In this paper, the authors used three hardened cement paste specimens composed of different air-void systems, and performed sensitivity analyses in terms of the number of traverse lines employed for a single section and the sampling sections across the height of a specimen.
