Öz
Design of structures that are inspired by the Nature is gaining attention in the latest year and many studies on the lattices of the materials are being conducted. And for designing, beams and truss structures are widely used elements. Thus, when designing new structures, getting inspired by those lattices and making use of those beams and trusses might prove to be advantageous. Maintaining the estimated lifetime of the structures is also an essential factor. So, it is essential to determine the characteristics of the structures such as the deflection, stresses and more. When determining those structures, finite element analysis can be used effectively. In this study, the lattice inspired models were constructed. Inverted L-frames, inverted U-frames and 3D frames were designed by using those models. Then to analyze those structures, finite elements method was used. The frames were subjected to four different input forces which were generated by using their total weight multiplied by 10, 20, 50, 100 coefficients. The results demonstrated that these designed structures can be used in many areas such as aviation, space, construction. Also, those structures can be used as the core part of the sandwich composites.
