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:

Discrete vs smeared crack models for concrete fracture: bridging the gap
TL;DR: In this article, discrete and smeared crack models for concrete fracture are discussed in a historical perspective, and it is argued that these two computational approaches, originally conceived as very different, can be brought together by exploiting the partition-of-unity property of finite element shape functions.

Shear fracture tests of concrete
TL;DR: In this article, the authors show that cracks do not propagate from the notches in the direction normal to the maximum principal stress but in a direction in which shear stresses dominate.

Monte Carlo simulation of complex cohesive fracture in random heterogeneous quasi-brittle materials
TL;DR: In this paper, a numerical method is developed to simulate complex two-dimensional crack propagation in quasi-brittle materials considering random heterogeneous fracture properties, where potential cracks are represented by pre-inserted cohesive elements with tension and shear softening constitutive laws modelled by spatially-varying Weibull random fields.

Fracture properties of geopolymer paste and concrete
TL;DR: In this paper, the fracture properties of fly ash-based geopolymer concrete and paste with various mix parameters were investigated and it was found that the fracture energy and brittleness of the fly ash concrete is correlated with its compressive strength.

Modelling of cohesive crack growth in concrete structures with the extended finite element method
TL;DR: In this paper, the extended finite element method (XFEM) is used for a discrete crack simulation of concrete using an adaptive crack growth algorithm, and different criteria for predicting the direction of the extension of a cohesive crack are investigated in the context of the XFEM.
