TLDR
In this article, the response of a finite-width composite laminate under uniform axial strain is treated through the application of classical elasticity theory, and finite-difference solution techniques are employed to obtain solutions for stresses and displacements throughout the region.Abstract:
The response of a finite-width composite laminate under uniform axial strain is treated through the application of classical elasticity theory. Finite-difference solution techniques are employed to obtain solutions for stresses and displacements throughout the region. Results for material properties typical of a high modulus graphite-epoxy composite material system are presented which explain the mechanism of shear transfer within a symmetric laminate. In addition, results of this work are compared to those given in a recent approximate formulation.read more

TL;DR: In this article, the case of a cracked ply embedded in a stratified composite is examined, with given assumptions on the toughness of the components and of the interface, the crack can propagate to become a delamination crack (i.e. lying at the interface between the components).

Failure, Cracks, Fracture, Fatigue, Delamination, Adhesion, and Cohesion
TL;DR: In this paper, the Griffith theory, surface energy, and stress intensity factors for fracture in modes I, II and III are described, as well as several failure criteria and necessary elements of the fracture mechanics, such as cracks.
An efficient semi-analytical finite fracture mechanics approach for the prediction of interlaminar crack initiation in composite laminates.
TL;DR: In this article, the authors proposed a semi-analytical scaled boundary finite element method (SBFEM) to predict interlaminar crack onset in composite laminates using FFM.

Determination of Interlaminar Stress Components in a Pretwisted Composite Strip by VAM
TL;DR: In this paper, the authors developed an efficient analytical approach to obtain the 3D elasticity solutions by using recovery relations through 1-D analyses, which is based upon the stress distribution from more appropriate, sophisticated and simple polynomials on the equilibrium equation of elasticity.

TL;DR: In this article, an analysis of interlaminar shear stresses is performed for a laminate under generalized plane stresses, where the laminate is modeled as a set of anisotropic layers separated by isotropic adhesive layers.
