TLDR
In this paper, a new general mixed-mode brittle fracture criterion based on the concept of maximum potential energy release rate (MPERR) was proposed, which can be easily degraded to the pure-mode fracture criterion and can also be reduced to the commonly accepted fracture criteria for the mixedmode I/II state.About:

Three-dimensional stress states at crack tip induced by shear and anti-plane loading
TL;DR: In this article, the authors provide an overview of recent theoretical studies carried out by the authors, which demonstrate that the account for these coupled modes can totally change the classical (two-dimensional) view on many fracture phenomena.

XFEM fracture analysis of composites
TL;DR: The first reference text for the extended finite element method (XFEM) for fracture analysis of composite structures and materials is as discussed by the authors, which describes the basics and developments of the new XFEM approach to fracture analysis.

3D crack propagation with cohesive elements in the extended finite element method
TL;DR: A robust way of introducing brittle non-smooth cohesive laws in the X-FEM by the a posteriori computation of the crack advance from the equilibrium, instead of a most common determination beforehand from the stress state ahead of the front.

A new fixture for fracture tests under mixed mode I/III loading
TL;DR: In this paper, a new loading fixture is suggested for exploring mixed mode I/III fracture experimentally, and the results of fracture toughness and fracture angles obtained from the experiments are in relatively good consistency with those predicted from the well-known maximum tangential stress criterion.

The Phenomena of Rupture and Flow in Solids
TL;DR: In this article, the authors investigated the effect of surface scratches on the mechanical strength of solids, and some general conclusions were reached which appear to have a direct bearing on the problem of rupture, from an engineering standpoint, and also on the larger question of the nature of intermolecular cohesion.

Strain-energy-density factor applied to mixed mode crack problems
TL;DR: In this paper, the authors investigated the general problem of crack extension in a combined stress field where a crack can grow in any arbitrary direction with reference to its original position, and showed that the direction of crack growth and fracture toughness for the mixed problem of Mode I and Mode II are governed by the critical value of the strain-energy-density factor.

TL;DR: In this article, the energy release rate for a crack subjected simultaneously to mode I and mode II conditions is computed by path independent integrals, using the elastic solution of a deflected crack, having a main branch and a propagation branch.
