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:

Design, testing and analysis of high ductile partial-strength steel-concrete composite beam-to-column joints
TL;DR: In this article, three-dimensional finite element models of an exterior and an interior joint subjected to horizontal loading are presented, taking into account the non-linear material properties of columns, end plates, reinforced concrete slabs and reinforcing bars which represent critical points of joint performance.

Probabilistic analysis of reinforced concrete frame structures against progressive collapse
Jia Liang Le,Bing Xue +1 more
TL;DR: In this article, a two-scale numerical model for assessing the risk of progressive collapse of reinforced concrete (RC) frame structures is presented, where the potential damage zones in various structural components, such as beams, columns and joint panels, are represented by a set of coarse-scale cohesive elements.

Thickness Effect on Fracture Energy of Cementitious Materials
TL;DR: In this article, a bilinear local fracture energy model was developed to characterize the ligament or back boundary effect on the fracture energy in the thickness direction, and the model was used to analyse available experimental data from the literature.

Cohesive zone models and impact damage predictions for composite structures
TL;DR: Existing cohesive zone models (CZM) and their use in numerical simulations for analysis impacts on composite structures and predicting the damage induced and applications for these models to other problems are surveyed.
