Nonlinear dynamic response of laminated composite plates subjected to pulse loading

An analytical solution methodology for the non-linear dynamic displacement response of laminated composite plates subjected to different types of pulse loading is presented. The mathematical formulation is based on third-order shear deformation plate theory and von-Karman non-linear kinematics. Fast-converging finite double Chebyshev series is employed for evaluating the displacement response. Houbolt time marching scheme is used for temporal discretization and quadratic extrapolation technique is used for linearization. The effects of magnitude and duration of the pulse load, boundary conditions and plate parameters on the central displacement and bending moment responses are studied.

► Nonlinear dynamic response of cross-ply symmetric laminated composite plates. ► Response due to blast, triangular and step loading. ► Fast converging finite double Chebyshev series. ► Applicable to non-classical (non-Levy type) boundary conditions also.
