Paper Number: ARMA-90-0629
... ABSTRACT INTRODUCTION: Shaped charges represent a special case of hypervelocity penetration in rocks and soils. They are commonly used to perforate well casings in the petroleum industry and are also in less frequent use in the mining industry. In this paper, we examine the penetration depth...
