Item TOPOLOGY OPTIMIZATION OF A SANDWICH STRUCTURAL COMPONENT AGAINST HIGH IMPULSE LOADINGS(2022-01-21) Şenel, Barkın; Aslan, Özgür; Baranoğlu, BesimSandwich structures are used in many areas today due to their lightness, economy and durability. Application in armoured military vehicles is one of these areas. Accord ing to previous studies in the literature, sandwich structures provide a great advantage over monolith structures. Today, researchers try to develop sandwich structures in terms of material or topology optimization to further increase this advantage. Nu merical analysis trials applied before experimental studies, on the other hand, help this development in terms of time and cost. In this thesis, different core geometry types selected are modelled in the SolidWorks package program. Then, the analy ses were made in the ABAQUS/Explicit finite element program. Initially, analyses were performed under fixed parameters for evaluation and comparison purposes only. According to the results, the material parameters were determined according to the material parameters to be used in production and the analyses continued in this way. However, in this study, no material optimization was made, only the topology was focused. In addition, while the geometries are modelled, it is aimed to determine the selected geometry types in a way that will not cause problems in terms of production. With these determined parameters and analyses, an optimum core geometry has been proposed, which is also easy in terms of production.
