Damage and fracture of a cross woven C/SiC composite subject to compression loading
In order to understand the mechanical behaviours of ceramic matrix composites under various loading conditions, the compression stress-strain behaviour of a cross woven C/SiC ceramic matrix composite was chara...

Interphase behaviour in graphite-thermoplastic monofilament composites
The fatigue properties of continuous filament composites are dependent on the fibre-matrix interphase behaviour, specifically the ability of the interphase to transfer load durably from the matrix to the fibre...

Interphase behaviour in graphite-thermoplastic monofilament composites
The role of the fibre-matrix interphase in transferring load from the matrix to the fibre in graphite-thermoplastic composites is not well understood. The goal of this work was to alter the interphase of graph...

Interfacial studies on carbon/thermoplastic model composites using laser Raman spectroscopy
Interfacial studies were carried out on a model composite system consisting of a short carbon fibre embedded in a polycarbonate matrix. While the composite was being strained, the local strain along the fibre ...

The mechanical behaviour of a cross-weave ceramic matrix composite
In order to find out whether or not a cross-weave ceramic composite, graphite fibre/SiC matrix, would be prone to fatigue failure, tests in pulsating tension and pulsating compression have been carried out wit...

Mechanical behaviour of a cross-weave ceramic matrix composite
The deformation and fracture processes of a cross-weave carbon fibre/SiC composite prepared by a chemical vapour deposition process has been explored by interrupted-loading tests and SEM examination of crackin...

Mechanisms of cyclic softening in precipitation-hardening alloys—A ball model approach and tests at 78 K
Tests of random, alternating cuts on a ball-model of θ″ in Al−Cu alloy have been run to check the kinetics at which disordering occurs in an initially ordered precipitate subject to cyclic strain. In addition,...

Transmission electron microscopy observations of misfit dislocations in GaAsP epitaxial films
Transmission electron microscopy observations have been made of misfit dislocation structures in GaAsP epitaxial films in foils both parallel to (1) the interface between the epitaxial film and the substrate a...

A theory of crack nucleation in high strain fatigue
From previous observations of the surfaces of metals cycled in high strain fatigue, the mechanism of crack nucleation is considered a plastic instability phenomenon. A model for crack nucleation based on this ...

On fatigue-induced reversion and overaging in dispersion strengthened alloy systems
The low fatigue strength/U.T.S. ratios of dispersion strengthened aluminum alloys may be explained by the presence of transgranular, precipitate-free bands in their microstructures. Since transgranular crack i...
