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

The use of interlayers in modeling interface crack propagation
TL;DR: In this article, the role of interlayer elastic modulus and thickness is examined in the context of a standard interface fracture test specimen and a scheme is outlined for the use of interlayers for predicting interface fracture in bimaterial systems such as laminated composites.

Local FEM Analysis of Composite Beams and Plates: Free-Edge effect and Incompatible Kinematics Coupling
TL;DR: In this paper, the authors compare different reduced models with their appropriate hypotheses in the thickness direction, which has a priori a singular behaviour, in order to have a comparable measurement of those singularities, the obtained stress distributions will be expressed via a power law function.

TL;DR: In this article, a deformable, finite element penalty formulation is developed for predicting stress fields, particularly interlaminar shear and normal stresses, in thick composite laminates and near a delaminated free edge in a laminated plate.

The Interlaminar Stresses at Straight Edges in Composite Laminates
TL;DR: In this paper, the authors used the features of anisotropic generalized plane stress theory to determine interlaminar stresses and derived the parameters of α and X in the stress expressions by requirement of stress integral equilibrium.

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.
