3D Printing and Numerical Modelling of Conch-Inspired Lamellar Structures
Abstract The research proposes a new structure which mimics the lamellar arrangement of conch-shell (strombus gigas). 3D printing is employed to mimic the conch inspired lamellar structure, which is effectively built by manipulating the G-Code printing instructions programmatically. This technique captures each layer of the second-order lamellar structure, which has variable orientation angles to effectively deflect and arrest cracks. The conch-inspired lamellar structure is proven to significantly dissipate energy by crack deflection under bending and tension compared to an equivalent monolithic specimen. A numerical model is subsequently developed, which utilises the extended finite element method (XFEM) in ABAQUS, to capture the damage mechanisms observed in experiment. The numerical and experimental results show good agreement, thereby warranting further research into novel lamellar designs for protective engineering applications.
