The failure behavior of geological materials depends heavily on confining pressure and
strain rate. Under a relatively low confining pressure, these materials tend to fail by brittle …

The bottom-hole pressure of hydraulic fracturing in ductile reservoirs is much higher than
that of the hydraulic fracturing simulation, and the fracture toughness inferred from the field …

Efforts towards producing low-carbon fossil fuels and renewable energy resources have
increased significantly within the last two decades and are expected to grow even more in …

In this paper, the recently proposed linear smoothed extended finite element method
(LSmXFEM) is employed to simulate the fatigue crack growth. Unlike the conventional …

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 not …

This article presents a fully coupled finite element method for the single cohesive fracture
propagation in a deformable porous medium (rock) interacting with two immiscible pore …

This paper reports improvements to algorithms for the simulation of 3‐D hydraulic fracturing
with the Generalized Finite Element Method (GFEM). Three optimizations are presented and …

In this work, a 2D pore pressure cohesive zone model is presented to simulate the hydraulic
fracture propagation in naturally fractured formation, in which the fracturing process is …

We present an extended finite element framework to numerically study competing hydraulic
fracture propagation. The framework is capable of modeling fully coupled hydraulic …

In this article, 3-D simulations of hydraulic fracture propagation with the Generalized Finite
Element Method (GFEM) are compared with several experiments. The GFEM in this work …
