The mechanical properties of solid polymers
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
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 asExpand

Measuring the fibre orientation and modelling the elastic properties of injection-moulded long-glass-fibre-reinforced nylon
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 thisExpand

The effect of hydrostatic pressure on the shear yield behaviour of polymers
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
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 fiberExpand

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 varyingExpand
