Stress fields in composite laminates
TL;DR: In this article, a new theory is proposed to define the complete stress field within an arbitrary composite laminate, based upon an extension of Reissner's variational principle to laminated bodies.

Compressive and torsional behaviour of Kevlar 49 fibre
TL;DR: In this article, the mechanical anisotropy of an aromatic polyamide fiber, Kevlar 49, was studied in tension, compression and torsion and fibres were shown to form regularly-spaced helical kink bands at 50 to 60° to the fiber axis after the application of small axial compressive strains.

Compressive strength of unidirectional composites
K.H. Lo,E.S.-M. Chim +1 more
TL;DR: In this paper, a combined analytical and semi-empirical approach is used to obtain a simple equation for predicting the compressive strength of unidirectional composites, based on the concept of microbuckling of a representative volume element in the composite, with the effect of shear deformation included.

A Parametric Study of Variables That Affect Fiber Microbuckling Initiation in Composite Laminates: Part 2 — Experiments
TL;DR: In this paper, the effects of the stacking sequence (orientation of plies adjacent to the 0-deg plies), free surfaces, fiber/matrix interfacial bond strength, initial fiber waviness, resin-rich regions, and nonlinear shear constitutive behavior of the resin on the initiation of fiber microbuckling in thermoplastic composites were investigated using nonlinear geometric and non-linear 2D finite-element analyses.

Mechanics of Incremental Deformation
Maurice A. Biot,D. C. Drucker +1 more
TL;DR: In this paper, the authors present an approach to non-linear elasticity which is characterized by the use of cartesian concepts and of elementary mathematical methods that do not require a knowledge of the tensor calculus or other more specialized techniques.
Mechanics of Composite Strengthening
TL;DR: In this article, the influence of fiber and matrix characteristics on mechanics of deformation and fracture of fibrous composite is discussed, and the authors propose a method to study the relationship between fiber properties and fracture properties.

A type of plastic deformation new in metals
TL;DR: In this article, it was shown that single-crystal wires of zinc or cadmium are extremely soft in general, and extremely hard as polycrystalline wires if the glide plane (0001) is nearly parallel to the wire axis, so that the usual glide mechanism cannot work in extension or bending.

TL;DR: Compressive strength and instability failure mechanism in uniaxial boron fiber-metal matrix composite material was discussed in this paper, where the authors proposed a failure mechanism for the composite material.
