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

Analysis, prediction, and prevention of edge delamination in rotor system structures
TL;DR: In this paper, it is concluded that free edge delamination can be managed by analysis and prevented by design, but in order to ensure durable composite structures, more work is needed to characterize delamination that occurs from other sources, such as matrix cracking and ply drops.

Adhesively bonded composite iosipescu specimens without singular stress fields
Y. Han,Maciej Kumosa +1 more
TL;DR: In this paper, the singular powers of serial wedge corners in adhesively bonded composite losipescu specimens have been studied using two-dimensional finite-element techniques and it has been shown that there are critical angles of the interfaces that separate the regions with positive and negative singular powers.

Influence of edge effects on the state of stress and strength of carbon composites in tension
TL;DR: In this paper, the theoretical strength of flat strips with straight edges, obtained on the basis of the two-dimensional solution within the elastic range for a composite with fiber angle ψ 30°, was compared with the actual strength obtained experimentally.

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.
