Dynamic Behavior of an Unevenly Heated Thin-Walled Parabolic Aircraft Shell Taking Into Account the Presence of Additional Mass under the Influence of a Shock Wave

The paper investigates the dynamic behavior of an unevenly heated thin-walled parabolic shell of rotation with additional mass under conditions of high-intensity shock wave loading in a gaseous medium. The stress-strain state of the shell resulting from the preliminary uneven heating of its surface is determined from the solution of the equations of thermoelastic equilibrium. The solution to the problem of dynamic behavior of a shell involves integrating the nonlinear motion equations of the shell, as well as the additional mass that is attached to it, under given the initial displacements, initial velocities of zero, and boundary conditions that correspond to the attachment of the shell.
