“…The consequences of the eccentricity of the stiffener, the number of stiffeners, and its positions were investigated on natural frequencies in that study. Geng et al [12] proposed a new numerical scheme to determine the stiffened-plate composite structures' mid-frequency and dynamic response. Balkan et al [13] examined the nonlinear dynamic behavior of a laminated composite stiffened plate subjected to the non-uniform blast and load.…”

Free vibration behavior of laminated composite plates stiffened by different lattice structures is considered. To simulate free vibration, finite element models were created with Ansys Parametric Design Language (APDL). In the models, SHELL181 and BEAM181 elements were used to model laminated composite and lattice structures, respectively. The influence of the different stiffeners lattice structures on natural frequencies of the composite plate is examined for the clamped-free-clamped-free boundary condition. The results showed that the frequency parameters of the stiffened composite structures made of the L2-type lattice are higher than those composed of other lattice types. This study provides an exciting opportunity to advance our knowledge of the usage of lattice structures as stiffener structures for composite plates.
