Journal ArticleDOI
Failure mechanisms of 3D woven composites in tension, compression, and bending
TL;DR: In this paper, the authors estimate the elastic moduli at which the first failure events occur in compression or tension, based on existing micromechanical models, which is a direct measure of damage tolerance and notch insensitivity.
Journal ArticleDOI
On the tensile failure of 3D woven composites
TL;DR: In this article, tensile tests for graphite/epoxy composites with three-dimensional woven interlock reinforcement are reported, showing that the lockup mechanism is the product of geometrical irregularity of nominally straight tows and clamping compressive stresses generated by the through-thickness reinforcement.
Journal ArticleDOI
The Macroscopic Elasticity of 3D Woven Composites
Brian N. Cox,Mahyar S. Dadkhah +1 more
TL;DR: In this paper, the elastic properties of graphite/epoxy composites with three-dimensional interlock weave reinforcement have been measured over length scales somewhat greater than the characteristic length of the weave pattern.
Journal ArticleDOI
Cracking and damage mechanisms in ceramic/metal multilayers
TL;DR: In this paper, the authors investigated cracking in multilayered ceramic/metal composites and found that the dominant cracking behavior depends on the volume fraction and yield strength of the metal.
Journal ArticleDOI
Mechanisms of compressive failure in 3D composites
TL;DR: In this paper, angle-interlock woven polymer matrix composite behavior under uniaxial monotonic compression was studied and shown to be macroscopically ductile, with compressive strains in failure that can exceed 15 percent.
