TL;DR: In this paper, a single fiber surrounded by the matrix and with a partial debonding is studied, and it is shown that under uniaxial loading transversal to the fibers direction, the most significant phenomena appear for semidebonding angles in the interval between 60 deg and 70 deg.

TL;DR: In this paper, a micromechanical analysis is performed using the Boundary Element Method, allowing contact between the debonded surfaces of fiber and matrix, and different combinations of loads are applied to check their influence in the energy release rate, which is the fracture parameter evaluated.

TL;DR: In this article, the authors investigated the mechanism of failure of a fibrous composite under tension transverse to the fibres and showed that the initial direction of failure predicted agrees with that observed in experiments, following a scheme of analysis of the damage mechanism analogous to that employed for the tension case.

TL;DR: In this paper, a numerical study is performed using the boundary element method aimed at explaining the origin and evolution of the damage at micromechanical level, considered as fibre-matrix interface cracks, assuming that the damage starts as small debonds originated by shear stresses at the position where their maximum values are reached.
