Abstract

Soft cellular structures are found extensively throughout nature and can be used to inspire the design of structures for a wide range of engineering applications. For many applications, such as soft tissue scaffolds, structure stiffness and density need to be optimised. This study aimed to investigate the effect of cell density for a constant material volume on structure behaviour and stiffness. An Imetrum video strain gauge system and a Dantec digital image correlation (DIC) system were used to capture structure deformation under tensile uniaxial loading. Results demonstrated that with an increase in cell density there was an increase in structure stiffness, with experimental results validating those found through Finite Element models (FEM).
