This study presents the continuous element formulation for analyzing the dynamic behavior of ring-stiffened cylindrical shells made of FGM material. Based on the solutions of the shell differential equations, the dynamic stiffness matrix is calculated. A procedure to assembly cylindrical and annular shells is introduced in order to compute the natural vibrational frequencies of FGM ring-stiffened cylindrical shells.

This paper presents the time history response of a sandwich beam with a porous core subjected to two moving harmonic loads with opposite directions. In the modelling, the beam is combined of two isotropic face sheets and a porous core with symmetric porosity distribution. The quasi-3D shear deformation beam theory in conjunction with Hamilton’s variational principle is utilized to set up the governing equations of motion. The Navier solution is used to obtain the displacement field.
