Possibility of compaction of explosion-produced high-velocity metal elements moving in a magnetic field

The accumulation of microdamage due to intense plastic deformation results in a decrease in the average density of high-velocity elements formed by explosive compression of shaped metal liners. For compaction of such elements in tests of the reliability of meteoroid protection, it is suggested that the elements be exposed to a magnetic field produced on their motion trajectory before interaction with a target. The physical processes occurring in a conducting elastoplastic porous cylinder placed in a magnetic field were studied by numerical modeling. The model was used to determine the parameters of magnetic-pulse action necessary for compaction of steel and aluminum elements.
