Cohesive Zone Models: A Critical Review of Traction-Separation Relationships Across Fracture Surfaces
TL;DR: In this article, potential-based models have been evaluated for mixed-mode cohesive fracture, and it is shown that these models lead to positive stiffness under certain separation paths, contrary to general cohesive fracture phenomena wherein the increase of separation generally results in the decrease of failure resistance across the fracture surface.

An extended finite element method for hydraulic fracture propagation in deformable porous media with the cohesive crack model
T. Mohammadnejad,Amir R. Khoei +1 more
TL;DR: In this article, a fully coupled numerical model is developed for the modeling of the hydraulic fracture propagation in porous media using the extended finite element method in conjunction with the cohesive crack model, where the fluid flow within the fracture is modeled using the Darcy law, in which the fracture permeability is assumed according to the well known cubic law.

Numerical simulations of fast crack growth in brittle solids
Xiaopeng Xu,Alan Needleman +1 more
TL;DR: In this article, a model of dynamic crack growth is presented for a plane strain block with an initial central crack subject to tensile loading, where crack branching emerges as a natural outcome of the initial-boundary value problem solution, without any ad hoc assumption regarding branching criteria.

A Continuum Model for Void Nucleation by Inclusion Debonding
TL;DR: In this paper, a boundary value problem simulating a periodic array of rigid spherical inclusions in an isotropically hardening elastic-viscoplastic matrix is analyzed and the effect of the triaxiality of the imposed stress state on nucleation is studied and the numerical results are related to the description of void nucleation within a phenomenological constitutive framework.
