Influence of cracks and voids on the responses of composites
Composite Structures, 2021Abstract In this paper, numerical study on influence of parameters related to cracks and voids on the responses of the composites under tension, compression, and shear deformation is conducted by extended finite element method (XFEM). Under tension, the maximum stress of composites changes less than 5 % when crack orientation, fiber ...

The Mechanical Properties of Metal-Void Composites [PDF]
, 1992 Abstract : Work under this contract is intended to conduct a theoretical feasibility study of the strength, toughness and vibrational damping properties of composite materials consisting of a metallic matrix with a high volume fraction (to 30%) of small (0.1 - 10 microns) pressurized voids. The premise of the approach is that a theoretical study, using

On the elimination of Kirkendall voids in superconducting composites
Applied Physics Letters, 1979Kirkendall void formation, which has hitherto prevented the use of the external diffusion technique for the manufacture of practical multifilamentary superconducting composites, can be suppressed by using solution anneals to eliminate sites for heterogeneous void nucleation.

Environmental Effects in Composite Laminates with Voids
Polymers and Polymer Composites, 1995This work presents an experimental program aimed at investigating some aspects of environmental effects on carbon/epoxy laminates with voids. The objective is to obtain experimental data to subsidize acceptance criteria for ultrasonic inspection of composite parts for aerospace applications.
