## Babakov V.## The Problem about Resistant Force for a Circular Striker and Composite Target
This paper considers low-speed penetration of an absolutely hard solid into a deformable obstruction (with a speed of encounter slower than the speed of sound in the obstruction) in which, unlike in high-speed collisions, the shape of the striker and the strength of the medium are essential. The study of the penetration process is a difficult mathematical problem, calling for the definition of an adequate mathematical model and, in most instances, computer calculations.
