DYNAMIC CARRYING-CAPACITY OF ELASTO-VISCO-PLASTIC CYLINDRICAL-SHELLS

We consider axially-compressed thin cylindrical shells, which deform e lasto-visco-plastically under high intensity external impulsive loadin g and in which volume damage can occur. The shell carrying capacity is determined in accordance with deformation, stability and strength cri teria. Our purpose is, introducing special dimensionless parameters, t o obtain the relation between the geometrical sizes and the material c haracteristics of the shell - on one hand and the dynamic impulse para meters (amplitude and duration) on the other, when the shells lose the ir carrying capacity.
