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

Estimation of transverse/interlaminar stresses in laminated composites – a selective review and survey of current developments
Tarun Kant,K. Swaminathan +1 more
TL;DR: In this article, a review is made on the different methods used for the estimation of transverse/interlaminar stresses in laminated composite plates and shells both analytical and numerical methods are considered In numerical methods, while the emphasis is given on finite element methods, other methods like the finite difference method is also briefly discussed Aspects considered are: effects of variation in geometric and material parameters, transverse shear and normal deformation, interface stress continuity and the interfacial bonding on the accuracy of prediction of cross-sectional and interlinear stresses.

Some Observations on the Interlaminar Strength of Composite Laminates
N. J. Pagano,R. Byron Pipes +1 more
TL;DR: In this article, a detailed design of a laminate specimen which can exhibit catastrophic delamination induced by interlaminar tension is presented, along with a preliminary failure hypothesis to characterize this mode of rupture and the associated experimental demonstration of the phenomena.

Size effects in the testing of fibre-composite materials
TL;DR: In this article, the effect of test specimen size on the unnotched strength of continuous fiber reinforced composites is considered, and different fundamental failure mechanisms of fibre direction tension, fibre direction compression, and matrix dominated transverse tension and shear are discussed in turn.
