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:

Experimental study on fracture and fatigue crack propagation processes in concrete based on DIC technology
TL;DR: In this paper, a method to determine crack tip position and fracture process zone (FPZ) in concrete was proposed based on Bažant Crack Band Model (CBM) and digital image correlation (DIC) technique.

Non-Linear Fracture Models for Discrete Crack Propagation
TL;DR: In this article, the proper fracture mechanics to be applied to crack propagation in concrete is determined by scale effects, based on the scale effects of scale effects in the original model of the crack propagation.

A novel rate-dependent cohesive-zone model combining damage and visco-elasticity
Marco Musto,Giulio Alfano +1 more
TL;DR: In this article, a rate-dependent cohesive-zone model combining damage and visco-elasticity was proposed based on two fundamental assumptions: the existence of an intrinsic (i.e., rate-independent) fracture energy and the evolution of the damage variable is related to the current free energy and to the intrinsic fracture energy.
