In this study, novel cellular structures designs are derived from venation patterns found in bird feathers. The designed structures are 3D printed using fused filament fabrication (FFF) method. All the structures are printed with acrylonitrile butadiene styrene (ABS) material. Printed structures are subjected to quasi-static tensile loading condition. In-situ digital image correlation technique (DIC) is used to study the fracture and crack propagation behavior in the cellular structures. Furthermore, finite element method (FEM) is also used to study the crack propagation and strain field contour. Here an attempt has been made to explore the possibility of engineering the crack path by controlling the design of the cellular structures. The novel designs showed local shear bands and based on the design it is possible to change the direction of shear bands. Furthermore, the effect of unit cell size and barbs angles of inclination on the crack propagation and mechanical properties is also studied. The increased length of the shear band can increase the post yielding strain, fracture energy and fracture toughness, which reduces the chances of sudden global failure of the structures. Hence this study opens an avenue for the advanced functional materials with tunable and fail-proof designs.
