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:

Decohesion finite element with enriched basis functions for delamination
TL;DR: In this paper, the mixedmode interface finite element is enriched with the analytical solution of an idealized beam on elastic foundation, and the partition of unity (PU) method is utilized to obtain the enhanced interpolation, implemented with two user elements.
