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:

Finite element simulation of ring expansion and fragmentation: The capturing of length and time scales through cohesive models of fracture
TL;DR: In this article, the expanding ring test of Grady and Benson (1983) is taken as a convenient yet challenging validation problem for assessing the fidelity of cohesive models in situations involving ductile dynamical fracture.

Mixed mode fracture of concrete
TL;DR: In this article, the authors extended the cohesive crack model to mixed mode propagation and an experimental confirmation is provided by testing four-point shear specimens of concrete, where a constant crack mouth sliding displacement rate is imposed, so that is is possible to control and detect the snapback load vs deflection branches.

TL;DR: A phase-field model for brittle fracture is implemented in the commercial finite element software Abaqus by means of UEL and UMAT subroutines and removes the need for numerical tracking of discontinuities in the displacement field that are characteristic of discrete crack methods.

Development of the fracture-based flexibility index for asphalt concrete cracking potential using modified semi-circle bending test parameters
TL;DR: In this paper, a fracture energy and flexibility index (FI) was proposed to screen asphalt concrete mixtures' cracking resistance using the semi-circular bending test geometry, and the results indicated positive correlation between SCB test results and other independent fatigue tests.
