Therefore, the scaffolds that they are designed for bone defects replacement should also be tested under the same loading conditions. In this study, the torsional behaviour of the scaffolds was investigated using four different lattice-based architectures. The scaffolds were designed in three porosity levels of 60%, 75% and 90%. Therefore, twelve models of the scaffolds were obtained. To determine their performance under torsional loading, the shear modulus of each model was calculated using finite element analysis. The results showed that in the scaffolds with lower porosity the scaffold's architecture does not play a main role in the shear modulus. However, in scaffolds with a porosity of 90%, the shear modulus was affected by the architecture of the scaffold. For example, a scaffold with an octet structure showed three times higher shear modulus in compare to a scaffold with a truncated-octahedron architecture. As a conclusion in the design of scaffolds with high porosity, scaffold architecture plays an important role in its torsional behaviour and should be considered as a design parameter. The results of this study showed that the torsional behaviour of scaffolds depends on both porosity and architecture. © 2020 IEEE.eninfo:eu-repo/semantics/closedAccessFinite Element AnalysisScaffold for BoneShear ModulusTorsional loadingConference Object10.1109/TIPTEKNO50054.2020.92992932-s2.0-85099469934N/A
