摘要：

On two size types of the semispherical three-layered structures, impact of the surface curvature and impact of the pulse dynamic loading on the stress-strain state (SSS) of these structures has been investigated. Values of normal stresses and vertical displacements of the structures' bearing layers and distribution of these indicators along the spatial coordinate have been determined. A finite element calculation method implemented within the software calculation complex NASTRAN has been applied.
