Analytical Investigation on Optimum Member Angle of Lattice Truss Structures

Abstract:

Metallic sandwich panels based on lattice truss structure have been developed for a wide range of potential applications with their lightweight and multi-functionality. The study focused on the analytical approach to investigate compression and shear characteristics of pyramidal and tetrahedral truss unit cells. With various unit cell models which have the same weight per unit area but different member angle, analytical solutions for effective stiffness and strength have been predicted and compared with each other. The results showed that there are the most optimal core configuration to maximize effective mechanical properties.
