Abstract
A method for measuring the time of crack formation in shock impacted m etals has been developed. The method is based on measuring resistivity changes in an impacted bar in a four-contact configuration. Experimen ts were performed with steel impactors fired in a gas gun on steel bar s. The results may be matched to computer simulations to obtain high s train rate dynamic parameters.
