| 英文摘要 | The characteristic and mechanism of damaging of ultra-high strength steel target penetrated by shaped charged jet are investigated. The results show that the temperature of the white etching layer near the punching hole of the target is above the transformation point during penetrating. So the mixing structure of the martensite and austenite with about 20 nm is formed. The severe shearing in the adiabatic shearing band (ASB) occurs only within 2 mum in thickness. The average shear strain of localizing shearing deformation zone (LSDZ) of a ASB is estimated as 110 and its minimum strain rate 2.24x10(6) s(-1). Usually the thickness of the ASB observed by miroscope consists of the LSDZ and its heat affect zone (HAZ). During the penetration of the shaped charged jet, several processes take place as follows: total flow plastic deformation near the punching hole along the direction of shaped charged jet moving, shearing fracture and partly melting of the target material on the interface between the target and shaped charged jet, shearing deformation located in a very narrow region as well as tensile fracture due to stress wave reflection on the surface of the target. |
