Models of fiber debonding and pullout in brittle composites with friction
TLDR
In this article, the debonding process of a fiber embedded in a brittle matrix is modeled as a mode 2 crack, where the elastic properties of the fiber are assumed to be transversely isotropic about the fiber axis.About:

The thermomechanical integrity of thin films and multilayers
TL;DR: In this paper, the principles of fail-safe thermomechanical design, based on the damage mechanisms known to occur in these systems, are discussed, including delamination and crazing of brittle layers.
Journal ArticleDOI
Friction modeling for dynamic system simulation
TL;DR: It is clear that multi-scale effects can dominate performance of friction contacts, and as a result more research is needed into computational tools and approaches capable of resolving the diverse length scales present in many practical problems.

Interface crack between two elastic layers
Zhigang Suo,John W. Hutchinson +1 more
TL;DR: In this article, a semi-infinite interface crack between two infinite isotropic elastic layers under general edge loading conditions is considered and the problem can be solved analytically except for a single real scalar independent of loading, which is then extracted from the numerical solution for one particular loading combination.

Fracture of fiber-reinforced materials
Y-Ch. Gao,Y-M. Mai,B. Cotterell +2 more
TL;DR: In this article, the fracture toughness of fiber-reinforced materials due to fiber debonding, frictional dissipation at the fiber-matrix interface following debonding and other micro-fracture mechanisms is discussed with reference to strong and weak fibres.

Journal ArticleDOI
The edge cracking and spalling of brittle plates
TL;DR: In this paper, a steady state crack growth region has been identified wherein the cracks propagate parallel to the side surface and the general trends in cracking were found to be broadly consistent with predicted behavior governed by a zero mode II criterion and assuming that the cracks grow into a steady-state trajectory.

Effect of Interface Mechanical Properties on Pullout in a SiC-Fiber-Reinforced Lithium Aluminum Silicate Glass-Ceramic
TL;DR: In this article, the pullout of fibers in the crack wake makes an important contribution to the toughness of ceramic-matrix composites, and pullout is influenced by the properties of the fibers and by the sliding resistance of the interface.
