Abstract

Shaped Charge's penetration performance is depended on the shape of warhead and explosive, liner materials. The liner that manufactured to small homogeneous grain increase the penetration performance and decrease the deviation of penetration performance. This texture is obtained by forging process but, creating the process that remove crack and get small homogeneous grain is very hard. In this study, We success to get the homogeneous small grain texture through appling the most suitable process by DEFORM CODE analysis.
