Shaped charge jet formation
WebbShaped Charge. Shaped charges are devices in which an explosive load is used to collapse a (usually metal) liner, thereby creating a high velocity jet that is capable of penetrating … WebbIt is concluded that the material and structure of the liner have a significant influence on the shaped charge jet and its penetration effect, which then affects the damage-induced fracture formation and extension in shale.
