Abstract

Compressive property of lattice material with pyramidal truss core was investigated under uniform quasi-static compression. Load–displacement response and shape deformations of trusses during compressive loading was simulated by finite element method. The numerical prediction is in good agreement with experimental measurement. Result showed that the compressive process of pyramidal lattice material consist of linear elastic, plastic buckling, secondary contact, softening and densification. Compressive property of lattice material with different truss configuration are compared. Peak compressive stress of lattice material with same relative density depend on the moment of inertia of truss configuration. Truss configuration with higher moment of inertia, can bear higher load.
