TLDR
In this article, a new generalized Timoshenko beam model was developed for a two-dimensional periodic matrix-fiber-matrix laminate and a new mechanism based on shear instability of matrix was proposed for kink band formation and a simple formula was then derived to predict the kink angle.About:

Damage and Failure of Composite Materials
TL;DR: In this paper, the authors provide a complete guide to composite material damage, fatigue, and failure, focusing on the underlying principles governing composite damage, reviewing basic equations and mechanics theory, before describing mechanisms of damage such as cracking, breakage and buckling.

Compressive Failure of Fiber Composites under Multi-Axial Loading
TL;DR: In this paper, the compressive strength of a fiber reinforced lamina under multiaxial stress states was examined and an equilibrium analysis was carried out in which a kinked band of rotated fibers, described by two angles, is sandwiched between two regions in which the fibers are nominally straight.

Modeling of strength degradation for fiber-reinforced polymer composites in fire
Yu Bai,Thomas Keller +1 more
TL;DR: In this paper, a model for predicting composite material strength degradation under elevated and high temperatures is proposed, which is based on the morphology of the mixture of materials in different states, and the degradation of nominal compressive strength tends to follow the lower bound of strength defined by the inverse rule of mixture.

Inter-fiber stresses in composites with carbon nanotube grafted and coated fibers
TL;DR: In this article, two types of morphologies are investigated: (1) CNTs grown on fibers; and (2) cNTs deposited in fiber coatings, where the difference in the two cases is the orientation of CNT near the fiber interface: radial for grown CNT and tangent for CNT in the coatings.

The Effect of Fiber Diameter on the Compressive Strength of Composites - A 3D Finite Element Based Study
TL;DR: In this article, a 3D finite element-based study of the compression response of unidirectional fiber reinforced polymer matrix composites (FRPC) is presented, which highlights the role of fiber diameter on the compressive response of FRPC.

Compressive failure of fibre composites
TL;DR: In this article, a review of experimental data and elementary theoretical formulas for compressive failure of polymer matrix fiber composites indicates that the dominant failure mode is by plastic kinking, which plays a central role in the local fiber misalignment.
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.
