Golovko K. Axially symmetric vibrations of discretely reinforced shell elements of structures on elastic foundation under pulsed loads

The objects of investigation are vibrations of discretely reinforced shells on elastic foundation under action of pulsed forsces. In dissertation the elaboration and realization of numerical approach to analysis of dynamic behavior of discretely reinforced shells with arial symmetry are performed. It is supposed thet the shell contacts with external medium under nonstationary loads. The problems about axially symmetric vibrations of discretely reinforsed cylindrical and spherical shells on one - and two-parametric elastic foundation are solved on the on the basis of integro-differential method with the us of elaborated numerical algorithms. The analysis of influence of the ambient elastic medium property and the reinforcing ribs arrangement on the mechanical effects in the heterogeneous shell structure elements is performed.
