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

Superposition Method for Analysis of Free-Edge Stresses
John D. Whitcomb,Ivatury S. Raju +1 more
TL;DR: In this article, the edge stress problem for composite laminates was transformed into a more lucid form by eliminating loads and stresses not contributing to interlaminar stresses, and a technique for approximate analysis using a two dimensional plane strain analysis was developed.

Assessment of plate theories for free-edge effects
TL;DR: In this paper, a comparative study of several laminated plate theories with respect to their capability to capture the steep transverse stress gradients occurring in vicinity of free edges is presented.

Prediction of peripheral tears in the anulus of the intervertebral disc.
TL;DR: In this paper, the authors investigated the mechanical behavior of lumbar spine segments under extension with compressive preload by the finite-element method and found that layer failure in the anterior outer anulus could occur in the early stage of life during extension with preload.

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.
