A dynamic system consisting of a thin square cantilever plate is shown in Figure 1. Time-variation of the load is selected: harmonic loads containing single frequency. Load is uniformly distributed spatially and applied in the transverse direction of the plate. The peak displacement and stress are obtained in the frequency domain. The results are obtained at the center point using direct method. The results from the NAFEMS benchmark problems are taken as reference.
