Impact of geometric parameters and physical-mechanical properties of the internal bearing layer on the dynamic transient processes of the three-layer hemispherical shell

The effect of geometrical parameters and physical-mechanical properties the internal bearing layer a three-layer spherical structure on its dynamic behavior under impulse loading was investigated. A finite-element model created calculations normal deflections stresses layers were performed using Fimap with NX Nastran software calculation complex. Options for reducing negative impact inefficient design solutions are considered.
 Geometric physical mechanical shell significant.
