Interaction of compression waves with an elastic spherical dome
Abstract
Simple models are proposed for the aeroelastic problem of the interaction of a weak shock wave with a thin shell. A method for calculating averaged loads in the case of the action of a weak shock on a spherical dome, developed previously by the authors (1989), is used to determine the displacement of points on the elastic dome and to calculate the shear stress on the shell's frame. In addition, formulas are obtained for calculating excess pressures associated with the passage of a shock wave through the elastic shell, taking transmitted and reflected waves into account. These formulas make it possible to develop a more precise aeroelastic model of wave/dome interaction.
