Analysis of crack formation and crack growth in concrete by means of fracture mechanics and finite elements
TLDR
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.About:

Assessing fracturing mechanisms and evolution of excavation damaged zone of tunnels in interlocked rock masses at high stresses using a finite-discrete element approach
TL;DR: In this paper, the impact of joint network geometry, joint strength and applied field stresses on the rock mass behaviors and the evolution of excavation induced damage due to the loss of confinement as a tunnel face advances was analyzed using the finite-discrete element method.

A new generalized finite element method for two-scale simulations of propagating cohesive fractures in 3-D
TL;DR: In this paper, a non-linear cohesive law is adopted to capture objectively the dissipated energy during the process of material degradation without the need of adaptive remeshing at the macro scale or artificial regularization parameters.

The effect of cohesive-law parameters on mixed-mode fracture
Ryan B. Sills,M.D. Thouless +1 more
TL;DR: In this article, a phase angle for interfacial fracture is calculated for a cohesive-zone model, and it is shown that if the cohesive length is small enough, the phase angle agrees with the value predicted by linear-elastic fracture mechanics, irrespective of the shape of the cohesive-laws.
