Abstract The plastic deformation behaviour of linear polyethylene and polyoxmethylene has been studied as a function of strain rate over a very wide range of plastic strains (deformation ratios up to ∼ 25). The results have been examined in terms of the concept of a true stress-strain-strain rate relationship. It has been shown that results for drawn fibres and extruded rods are compatible on this basis, and true stress-strain-strain rate surfaces can be defined. The significance of these results with regard to both tensile drawing and hydrostatic extrusion processes is considered. A preliminary discussion of the rate dependence is also presented.
