Dynamic Modeeling Of Rock Crushing Process

Crushing behaviour of thinwalled elements becomes an important problem of the modern engineering analysis and concerns particularly dynamic crushing of thinwalled structures the term dynamic crushing is used in the present paper in the sense of progressive crushing of a structure subject to impulse of an applied load.
