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:

Masonry compression: a numerical investigation at the meso‐level
TL;DR: In this paper, an alternative phenomenological approach developed in a discrete framework is proposed, based on attributing to masonry components a fictitious micro-structure composed of linear elastic particles separated by nonlinear interface elements.

Size effect on flexural, splitting tensile, and torsional strengths of high-strength concrete
TL;DR: In this article, the size effect on flexural, splitting tensile, and torsional strengths of high-strength concrete (HSC) with normal aggregate (crushed limestone) and lightweight aggregate (sintered fly ash) was investigated.

Cohesive Fracture Model Based on Necking
Zhi-He Jin,C.T. Sun +1 more
TL;DR: In this article, the authors used an integral equation approach together with the cohesive crack assumption, and found that in order to remove the stress singularity at the tip of the cohesive zone, the cohesive law must have a nonzero traction at the initial zero opening displacement.

An embedded cohesive crack model for finite element analysis of mixed mode fracture of concrete
TL;DR: In this article, an embedded cohesive crack model is proposed for the analysis of the mixed mode fracture of concrete in the framework of the Finite Element Method, which only requires the elastic constants and the mode I softening curve.

Behaviour and design calculations on very slender thin-walled CFST columns
TL;DR: In this paper, the behavior of very slender thin-walled concrete-filled steel tubular (CFST) columns under axial compression was studied and the reliability analysis method was used to calibrate the existing design formulas given in DBJ/T1351-2010, ANSI/AISC 360-05 and Eurocode 4.
