Characterization of Wave Propagation in Nonsymmetric Laminated Plates

This article presents a theoretical approach to predict the characterization of wave propagating in nonsymmetric laminated plates based on first-order shear deformation theory. It was developed as an extension of Mindlin theory including the effects of shear and rotary inertia. We formulated the equations of motion by substituting the deformations including three displacement functions and two rotary functions, and in any case of laminated plates, more precise wave velocities were calculated. We also described velocity frequency curves of waves in five modes from the numerical results and investigated the influence of the laminate angle, number of layers, and stacking sequence in detail.
