A framework for data-driven solution and parameter estimation of PDEs using conditional generative adversarial networks
Here we employ and adapt the image-to-image translation concept based on conditional
generative adversarial networks (cGAN) for learning a forward and an inverse solution …

A mixed-mode phase field fracture model in anisotropic rocks with consistent kinematics
Under a pure tensile loading, cracks in brittle, isotropic, and homogeneous materials often
propagate such that pure mode I kinematics are maintained at the crack tip. However …

Double-phase-field formulation for mixed-mode fracture in rocks
Cracking of rocks and rock-like materials exhibits a rich variety of patterns where tensile
(mode I) and shear (mode II) fractures are often interwoven. These mixed-mode fractures are …

Cam-Clay plasticity. Part IX: On the anisotropy, heterogeneity, and viscoplasticity of shale
We investigate three aspects of material behavior in this ninth installment of the Cam-Clay
series, namely, anisotropy, heterogeneity, and viscoplasticity. The main focus of the paper is …

Dynamic strain localization into a compaction band via a phase-field approach
We present a new phase-field formulation for the formation and propagation of a compaction
band in high-porosity rocks. Novel features of the proposed formulation include (a) the …

A phase-field model of frictional shear fracture in geologic materials
Geologic shear fractures such as faults and slip surfaces involve marked friction along the
discontinuities as they are subjected to significant confining pressures. This friction plays a …

Size effects on the strength and cracking behavior of flawed rocks under uniaxial compression: from laboratory scale to field scale
The failure behavior of field-scale rock masses has long been studied indirectly through
laboratory compression tests on rock specimens with preexisting flaws. However, little to no …
