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:

A loading rate dependent cohesive model for concrete fracture
Ángel de la Rosa,Ángel de la Rosa,Rena C. Yu,Gonzalo Ruiz,Luis Saucedo,Jose Luiz Antunes de Oliveira e Sousa +5 more
TL;DR: In this article, a time dependent cohesive model to account for the influence of loading rate on concrete fracture is addressed, and the model has been validated with results from three-point-bend notched specimens of high strength concrete, tested at five different loading rates.

An interface debonding law subject to viscous regularization for avoiding instability: Application to the delamination problems
TL;DR: In this article, a technique that can be used to introduce damping into cohesive zone finite element simulations of crack nucleation and growth, with a view to avoiding convergence difficulties in quasi-static finite element simulation is proposed.

Prediction of ceramic fracture with normal distribution pertinent to grain size
TL;DR: In this article, it was shown that the characteristic crack a*ch = 0.25(KIC/ft)2 ǫ/ǫ 2 ≈ 3, and the mean and standard deviation (σ) were determined by normal distributions for both the tensile strength ft and fracture toughness KIC.

A 3D multi-phase meso-scale model for modelling coupling of damage and transport properties in concrete
TL;DR: In this article, a 3D multi-phase meso-scale model is proposed to analyse the evolution of damage and transport properties in concrete, which includes aggregates, mortar, voids, cracking and interfacial transition zones (ITZs) between aggregates and mortar.

Smeared Crack Analysis for Plain Concrete in Torsion
TL;DR: In this article, the authors present an analytical model for the behavior of concrete elements in increasing torsion based on a special numerical technique that employs constitutive relations expressed in terms of normal stress and crack width, for the behaviour of the crack process zones.
