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.

Cohesive zone length in numerical simulations of composite delamination
Paul W Harper,Stephen R. Hallett +1 more
TL;DR: In this article, the authors highlight the limitations of existing formulae used to predict numerical cohesive zone length and demonstrate modifications necessary for improved accuracy, and provide a minimum number of interface elements within the cohesive zone.

Mixed mode cracking in layered materials
John W. Hutchinson,Zhigang Suo +1 more
TL;DR: In this article, the authors describe the mixed mode cracking in layered materials and elaborates some of the basic results on the characterization of crack tip fields and on the specification of interface toughness, showing that cracks in brittle, isotropic, homogeneous materials propagate such that pure mode I conditions are maintained at the crack tip.
