Abstract :Materials with lattice structure have been used in many engineering fields. However, studies including dynamic and static analysis of lattice structured beams are not common in literature. In this study, three types of cantilever beams with lattice structure were designed as 3 Dimensionally in nTopology software and analyzed in Ansys software. Square rotated, hexagonal and triangular type lattice structures were used in design of the beams. 10 Kilonewton force were applied to each beam and the displacements that were occurred at the free end side of the beams were recorded. Discrete time transfer function models, discrete time state space models and nonlinear Autoregressive with Extra Input models were obtained using input and output data set belongs to vibration of the beams. System Identification Toolbox of MATLAB was used to obtain the models. In addition, modal analysis and static analysis of the beams were realized. The results belong to system identification, modal analysis and static analysis were illustrated in figures, presented in tabular form and were discussed. After the non-lattice beam, the lowest specific deformation occurred in the triangular lattice beam. Therefore, the triangular lattice structure gave promising results for structural elements in pure bending state.
