The mechanical properties of solid polymers
- I. Ward, P. R. Pinnock
- Chemistry, Materials Science
- 1966
Several aspects of the mechanical properties of polymers are discussed. These include linear and non-linear viscoelastic behaviour, anisotropy, rubber-like elasticity, breaking and cold drawing.
Modelling of the energy absorption by polymer composites upon ballistic impact
- S. S. Morye, P. Hine, R. Duckett, D. Carr, I. Ward
- Materials Science
- 1 November 2000
Abstract In this paper we report on the development of a simple model for calculating the energy absorption by polymer composites upon ballistic impact. Three major components were identified as… Expand
Review: The yield behaviour of polymers
- I. Ward
- Materials Science
- 1 November 1971
Recent research on the yield behaviour of polymers is reviewed. Particular attention is given to the importance of the hydrostatic component of stress, the viscoelastic nature of the yield process,… Expand

Measuring the fibre orientation and modelling the elastic properties of injection-moulded long-glass-fibre-reinforced nylon
- P. Hine, N. Davidson, R. Duckett, I. Ward
- Materials Science
- 1995
Abstract This paper describes the characterisation of the 3D fibre orientation of a single-gated injection-moulded plaque of short-glass-fibre-reinforced Nylon by image analysis, and the use of this… Expand
The effect of hydrostatic pressure on the shear yield behaviour of polymers
- S. Rabinowitz, I. Ward, J. S. Parry
- Materials Science
- 1970
The torsional stress-strain behaviour of isotropic poly(methylmethacrylate) (P M M A), poly(ethylene terephthalate) (P E T) and polyethylene has been studied under hydrostatic pressures up to 7 kbar.… Expand
Fiber packing and elastic properties of a transversely random unidirectional glass/epoxy composite
- A. A. Gusev, P. Hine, I. Ward
- Materials Science
- 1 March 2000
Image analysis was used to characterize the microstructure of a unidirectional glass/epoxy composite which was found to be transversely randomly packed. Starting from a measured distribution of fiber… Expand
Optical and Mechanical Anisotropy in Crystalline Polymers
- I. Ward
- Materials Science
- 1 November 1962
Expressions have been derived for the optical birefringence and elastic moduli of an idealized semicrystalline polymer in terms of the molecular orientation. The predicted birefringence and moduli… Expand
The influence of morphology and molecular weight on ductile-brittle transitions in linear polyethylene
The tensile behaviour of linear polyethylene was examined over a wide range of temperatures. Samples were prepared from low and medium molecular weight polymer with different morphologies, by varying… Expand
