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:

Fracture process zone characteristics and identification of the micro-fracture phases in recycled concrete
Menghuan Guo,Syed Yasir Alam,A. Z. Bendimerad,Frédéric Grondin,Emmanuel Rozière,Ahmed Loukili +5 more
TL;DR: In this article, the influence of recycled aggregate proportion on the characteristics of fracture process was analyzed and three clusters correspond respectively to aggregate fracture, cracking in cement mortar and cracking at the interfacial transition zone were discriminated.

Numerical analysis of flexural strengthening of timber beams reinforced with CFRP strips
Mourad Khelifa,Alain Celzard +1 more
TL;DR: In this paper, the authors developed a numerical procedure to simulate the flexural behaviour until failure of CFRP-strengthened timber beams, and implemented it into Abaqus/Explicit using the Vumat user subroutine.

Fatigue Crack Propagation in Plain Concrete
TL;DR: In this article, the empirical Paris' Law for crack propagation in metals and rocks given by da/dN = C(ΔK)m is validated for use in crack propagation.

Applications of normal stress dominated cohesive zone models for mixed-mode crack simulation based on extended finite element methods
TL;DR: In this article, a cohesive zone model with a threshold is introduced and applied for simulating different mixed-mode cracks in combining with the extended finite element method, and the results of cracked specimens show that the crack initiation and propagation under mixedmode loading conditions can be characterized by the cohesive-zone model for normal stress failure.

Static and fatigue fracture mechanics properties of self-compacting concrete using three-point bending tests and wedge-splitting tests
TL;DR: In this article, the results of static and dynamic three-point bending tests and wedge-splitting tests on specimens, made from VC (vibrated concrete) and two types of SCC (self-compacting concrete), were compared.
