Abstract
The results of a series of high strain rate tests undertaken on cast iron and cast steel samples for the Defence Research Establishment Suffield are reported. The testing consisted of tensile and Taylor Cylinder experiments conducted to determine the constants in the Johnson and Cook exponential work hardening model for the Von Mises flow stress. It was concluded that the cast steels with no heat treatment are not suitable for high strain rate applications as significant cracking occurred during testing. The heat treated cast steels showed less cracking and may be useful in some applications. Cast irons exhibited more ductile behaviour and provided excellent results during tensile and Taylor cylinder testing.
