| Abstract: | The elastoplastic dynamic response of an infinite cylindrical shell to underwater explosive loading is proposed. According to the theory of fluid solid coupling and finite deformation of the cylindrical shell, the method of Fourier decomposition for the deflection and stresses is applied to the analysis of elastoplastic motion of the cylindrical shell, and equations are solved by a fourth Runge Kutta integration procedure. The analytical solution is obtained in the end. |
