The high strain-rate response of four readily available tissue simulants has been investigated via plate-impact experiments. Comparison of the shock response of gelatin, ballistic soap (both sub-dermal tissue simulants), lard (adipose layers) and Syl

Four samples of polyethylene terephthalate (PET), with different thermal histories were investigated by radial distribution function (RDF) methods. Intramolecular distances in the polymer repeat unit were successfully attributed to peaks in the RDF p

The thermal conductivities of unplasticized and plasticized samples of polyvinyl chloride have been measured in the range 15° to 98°C. At a temperature above about 25°C the thermal conductivity decreases with increasing plasticizer concentration,

A study has been made into some of the factors associated with the kinetics of the benzene-induced crystallization of polyethylene terephthalate. Four thicknesses of the film were used at temperatures of 25°, 30°, 35° and 40°C and in one case at

The influence of extrusion conditions on the benzene-induced and heat or ‘thermal’ crystallization of polyethylene terephthalate has been studied. Samples of film with extrusion rate/melt temperature properties of 70 270 , 155 270 , 75 280 , 160

The development of crystallinity in essentially amorphous polyethylene terephthalate film following immersion in a range of organic liquids at 25°C has been studied. The rate of development of crystallinity varies markedly with the liquid and althou
