Phase-field modeling of fracture
TL;DR: This chapter provides an extensive overview of the literature on the so-called phase-field fracture/damage models (PFMs), particularly, for quasi-static and dynamic fracture of brittle and quasi-brittle materials, from the points of view of a computational mechanician.

An explicit phase field method for brittle dynamic fracture
TL;DR: In this paper, an explicit phase field model for dynamic brittle fracture is proposed, where the mechanical field is integrated with a Verlet-velocity scheme, while the phase field is incremented with sub-steps at each step.

Phase field modeling of brittle compressive-shear fractures in rock-like materials: A new driving force and a hybrid formulation
TL;DR: In this article, a new phase field model that can simulate well compressive-shear fractures in rock-like materials was proposed, where only the compressive part of the strain is used in the new driving force with consideration of the influence of cohesion and internal friction angle.

On the BFGS monolithic algorithm for the unified phase field damage theory
TL;DR: This work proposes in this work, for the first time, to use the Broyden–Fletcher–Goldfarb–Shanno (BFGS) algorithm to solve in a monolithic manner the system of coupled governing equations, rather than the standard Newton one which is notoriously poor for problems involving non-convex energy functional.

Cracking elements method for dynamic brittle fracture
TL;DR: The cracking elements (CE) method is a self-propagating strong discontinuity embedded approach with the statically optimal symmetric (SDA-SOS) formulation for simulating the fracture of quasi-brittle materials.

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.

Yielding of steel sheets containing slits
TL;DR: In this article, a relation between extent of plastic yielding and external load applied was investigated, and panels containing internal and edge slits were loaded in tension and lengths of plastic zones were measured.
Analysis of crack formation and crack growth in concrete by means of fracture mechanics and finite elements
TL;DR: In this article, fracture mechanics is introduced into finite element analysis by means of a model where stresses are assumed to act across a crack as long as it is narrowly opened, which may be regarded as a way of expressing the energy adsorption in the energy balance approach.
