Transient wave propagation in the ring stiffened laminated composite cylindrical shells using the method of reverberation ray matrix

摘要: The method of reverberation ray matrix is extended to investigate the transient wave propagation and early short time responses ring stiffened laminated composite cylindrical shells subjected impact loads. are modeled as continuous coupling systems between vibration un-stiffened shell motion curved beams. dynamic models beams in Laplace phase space established on basis first order shear deformation theory. can be determined by boundary conditions shell. Using fast Fourier transform algorithm, computed. Through numerical simulations, it seen that accelerations under loads very large, while strains displacements small. Furthermore, influences stiffener number load types also investigated.
