In this article, the transient responses of the laminated composite sandwich plate structure are obtained numerically using the commercial finite element package to reduce the computational cost without hampering the accuracy. The plate structure is discretized using the available shell element (SHELL281) from ANSYS library. In order to compute the responses, an ANSYS parametric design language code has been developed based on the finite element steps and Newmark integration technique. The model accuracy and stability have been checked and few numerical examples have been solved. Finally, the effect of different parameters like side-to-thickness ratios, core-to-face thickness ratios, and lamination schemes are computed to show the necessary influences on the time-dependent deflection of the laminated composite sandwich structure.
