Inglese term
shaped charge
Conventional shaped charges are constructed with a charge case, a hollow conical liner within the case, and a high explosive material positioned between the liner and case. (globalsecurity.org)
Shaped charges were first developed after World War I to penetrate tanks and other armored equipment. Their most extensive use today is in the oil and gas industry where they open up the rock around drilled wells. (llnl.gov)
This source has been used since 1971 in routine seismic operation in the Amazon jungle with 300 gram unit charges distributed in small and large shot arrays increasing substantially the coverage and halving the cost at a higher record quality. A large amount of production seismic field work has been carried out in several other areas attesting the successful application of the shaped charges. (Wiley InterScience )

Proposed translations
carica cava, carica sagomata
Tra le miccie detonanti rientrano anche le miccie a carica cava, che servono per direzionare l’esplosione in modo tale da poter tagliare determinati materiali o strutture. (Esplosivi)
Successivamente, in Germania fu elaborata la realizzazione di missili anticarro guidati, con studi derivati dall'X-1 aria-aria; la testata prevista, come per tutti i successori, era a carica cava (HEAT), considerata la migliore per le armi leggere a bassa velocità. (Wikipedia)
Le pressioni che si raggiungono nella deflagrazione sono modeste ma diventano enormi quelle che si sviluppano nella detonazione. Queste ultime possono essere di 15000 - 20000 kg/cm² e con cariche sagomate e opportunamente preparate (cariche cave, cfr. n. 17.38) può superare di oltre 10 volte gli anzidetti valori.

: I agree. Technically hollow charge= carica cava shaped charge= carica sagomata
