STUDY OF TARGET PENETRATION PREDICTION BY HIGH SPEED AND ULTRA HIGH SPEED BALLISTIC IMPACT

Abstract

Following a general discussion of material properties under impulsive loading some justification is given for using available static and quasi-static material properties for correlation with hypervelocity impact cratering. A preliminary analysis of the correlation between depth of penetration and ten independent variables has been performed on the digital computer. Multiple correlation coefficients indicate a strong dependence of crater depth upon the tensile yield strength of the target relative to other independent variables. About 96% of the variance in crater depth may be explained by variations in the ten independent variables chosen for this first analysis.
