Dynamics of a spherical shell under a nonsymmetric internal pulse loading

TLDR: In this article, the elastic dynamic deformations of an air-filled spherical shell upon explosion of a lumped high energy charge in its cavity were investigated, and the authors concluded that there is no connection between the build-up of vibrations and the disturbance in the central symmetry of the load.

Abstract: These authors conduct experimental investigations of the elastic dynamic deformations of an air-filled spherical shell upon explosion of a lumped high energy charge in its cavity. A sketch illustrates the arrangement of the steel shell with ball charge and strain gauges; oscillograms show the pressure measurements on the outer and inner surfaces; and a table records shell strain as a function of eccentricity. The authors conclude that there is no connection between the build-up of vibrations and the disturbance in the central symmetry of the load.
