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

A composite beam theory for modeling nonlinear shear behavior
Fang Jiang,Ankit Deo,Wenbin Yu +2 more
TL;DR: In this paper, a variational asymptotic beam model is developed for the purpose of modeling physically nonlinear elastic behaviors of a material point in the structure, which are essential to the further analyses which are beyond the linear elasticity regime, for example, the progressive damage and failure.

Dynamic Transverse Debonding of a Single Fiber
TL;DR: By integrating a Kolsky tension bar along with a high-speed x-ray phase contrast imaging method and a high speed optical camera, high strain rate debonding processes of an opaque composite composed of a single S-2 fiber and SC-15 epoxy resin is recorded in real time and analyzed as discussed by the authors.

TL;DR: In this article, a global-local finite element stress analysis is utilized to examine the possibility of compression failure and a successive sub-modeling approach that allows detailed analysis of the inter-laminar stresses in regions of high stress gradients, including free edges and tapered laminates.
