Fatigue driven delamination in composite structures: definition and assessment of a novel fracture mechanics based computational tool
TL;DR: In this paper , the authors developed a robust and efficient computational tool to simulate the fatigue driven delamination in complex composite structures by exploiting the peculiarities, in terms of mesh and load step size independency, of the well-established SMart-time XB procedure, based on the Virtual Crack Closure Technique approach, to develop a Paris Law-based module to mimic the delamination growth rate due to cyclic loads.

TL;DR: In this paper , the failure mechanism in simple glass laminate aluminum reinforced epoxy (GLARE) was delamination, however, in open-hole GLARE, no delamination occurred except for some areas around the hole, and the specimen was broken in the hole area.

A numerical study on the effect of delamination on composite cylindrical shells subjected to hydrostatic pressure
TL;DR: In this article , a model of the composite shell with initial delamination and geometric imperfection is elaborated numerically by using the finite element method and the virtual crack closure technique is employed to calculate the strain energy release rate, and the linear fracture criterion is used to determine the onset and growth of the delamination.

Theories and Finite Elements for Multilayered, Anisotropic, Composite Plates and Shells
TL;DR: In this article, an overview of available theories and finite elements that have been developed for multilayered, anisotropic, composite plate and shell structures is presented. But, although a comprehensive description of several techniques and approaches is given, most of this paper has been devoted to the so called axiomatic theories and related finite element implementations.
