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:

Prediction of hole expansion ratio for automotive grade steels
TL;DR: In this paper, the hole expansion ratio of steel sheets from uniaxial tensile properties is characterized experimentally and predict analytically from the true fracture strain, considering that the test stop criteria of hole expansion process is the formation of a through thickness crack.

Fracture process zone in cementitious materials
TL;DR: In this article, the measurement and prediction of the fracture process zone (FPZ) with the compliance method with a multi-cutting technique is presented. But the method is not applicable to cementitious materials.

Geometric damage tensor based on microplane model
TL;DR: The microplane models provide conceptual simplicity and close fits of multiaxial test data for concrete, soils, etc., although, as formulated in the past, various kinds of physical phenomena were mixed in the definition of the microplane stress‐str...

Effect of fracture path on the fracture energy of high-strength concrete
An Yan,Keru Wu,Dong Zhang,Wu Yao +3 more
TL;DR: In this paper, the authors used the fractal theory to quantitatively study the fracture surface and the relationship between fracture energy and fracture characteristics, and found that fractal dimension increases with the increase of maximum aggregate size.

Evaluation of minimum reinforcement ratio in FRC members and application to tunnel linings
TL;DR: In this article, a nonlinear model is proposed to calculate a reinforcement area lower than that calculated according to Eurocode 2 and Rilem TC 162-TDF prescriptions, and a new approach for the evaluation of minimum reinforcement area is proposed.
