Abstract
This study was prepared on the bending and buckling analyses of the 2D honeycomb structure beam with a pocket section on it. In the study, two different materials,PLA and ABS, were selected to be examined for the beam. The aim of the study was to determine the buckling modes and critical buckling loads of lattice beams using numerical methods. Besides, bending analyses were conducted. As a result of bending analyses, the displacement (u y ), equivalent von Mises stress (σ von ), shear stress (τ xy ) and normal stress (σ y y ) behaviours for two different materials were obtained. It was determined that the ABS material deformed more than the PLA material beam. In this direction, important findings were obtained for understanding the bending and buckling behavior of lattice beams.
