Abstract

In this study, a theoretical analysis for predicting the mechanical properties of three dimensional lattice structures under compressive loading is proposed, and verified by comparing the analytical predictions with FEM results. This theory for estimating the initial stiffness E* is based on the classical beam theory, and the one for estimating the plastic collapse strength σ*pl reflects the stress state for each lattice structure. In particular, effects of inner geometry (strand's diameter-to-length ratio and micro-architecture) on the mechanical behaviour are discussed.
