Kumchol Yun,Zhenqing Wang,Mengzhou Chang,Jingbiao Liu,Tae-Jong Kim,Nam-Jin Son,Kyongsu Ji,Sakaya Ronald +7 more
TL;DR: In this article, an efficient and simple methodologies for simulating the three dimensional (3D) quasi-brittle fracture problems is presented. But the method does not identify the crack plane within each element, but it couples well with smeared crack method by identifying all the elements through which the crack surface passes.

Finite element interface models for the delamination analysis of laminated composites: mechanical and computational issues
Giulio Alfano,M. A. Crisfield +1 more
TL;DR: In this paper, a finite element analysis of delamination in laminated composites is addressed using interface elements and an interface damage law, where the principles of linear elastic fracture mechanics are indirectly used by equating the area underneath the traction/relative displacement curve to the critical energy release rate of the mode under examination.
