TLDR
In this article, the shear within a matrix volume is assumed to be an important process during the creep of composite material reinforced with short rigid fibres, and the rate of elongation of such a composite with certain fibre distributions can be estimated.Abstract:
The shear within a matrix volume is assumed to be an important process during the creep of composite material reinforced with short rigid fibres. The rate of elongation of such a composite with certain fibre distributions can be estimated. The agreement with a few experimental data is reasonably good.read more

The physics and mechanics of fibre-reinforced brittle matrix composites
Anthony G. Evans,Frank W. Zok +1 more
TL;DR: In this paper, a review of the mechanical and structural performance of brittle matrix composites is presented, focusing on the stress/strain behaviour in tension and shear, the ultimate tensile strength and notch sensitivity, fatigue, stress corrosion and creep.

Creep behavior of discontinuous SiCAl composites
TL;DR: A review of creep data of discontinuous SiCAl composites (whisker and particulate) shows that the creep behavior of these composites exhibits two main characteristics: (a) the stress dependence of the steady state (or minimum) creep rate, as described by the value of the stress exponent, is high and variable; and (b) the temperature dependence, measured by the creep activation energy, is much larger than that for self-diffusion in aluminum.

Interfacial slip and damping in fibre reinforced composites
D. J. Nelson,J.W. Hancock +1 more
TL;DR: In this article, the effect of interfacial slip on the stress properties of a polymer reinforced with short fibres is discussed with particular reference to hysteresis, and the amount of energy dissipated by interface sliding and by the viscoelastic response of the matrix is calculated in the light of a simple model.

Creep behaviour of a Ni-Ni3Al-Cr3C2 eutectic composite
E Bullock,M. McLean,D.E Miles +2 more
TL;DR: In this paper, the creep behavior of a Ni-Ni3Al-Cr3C2 directionally solidified eutectic composite was investigated at 825 and 980°C and found to be sensitive to the scale of the microstructure, which is dependent on both the rate of solidification and on the temperature gradient.

Role of interfaces in creep of fibre-reinforced metal-matrix composites—II short fibres
TL;DR: In this paper, the effects of the deformation characteristics of fiber-matrix interfaces are considered in a model of creep in aligned short-fibre reinforced composites, where the fibres are assumed to extend elastically and the matrix is subjected to power-law creep.

Tensile properties of fibre reinforced metals—II. Creep of silver-tungsten
Anthony Kelly,W.R. Tyson +1 more
TL;DR: The rate of creep of composites containing discontinuous wires appears to be governed by the action of the shear stresses which arise close to the fiber-matrix interface as mentioned in this paper.

On the creep behavior of silver—I. The oxygen free metal
TL;DR: The creep behavior of 99.9993% oxygen free, silver has been studied in vacua at 250, 400 and 550°C as mentioned in this paper, and it was found that voids first appeared at about the start of the secondary stage, increasing linearly with creep strain thereafter.
