Abstract
In this paper, a theoretical analysis for predicting the mechanical properties of lattice structures under compressive loading is proposed, and verified by comparing the analytical predictions with FEM results. This theory for estimating E^* is based on the classical beam theory, and the one for estimating σ^*_<pl> reflects the stress state for each lattice structure. It is found that the BCC structure is a bending-domminated structure, and the BCCZ structure is a compressing-dominated structure, and the f_2BCC structure is a mixed loading-dominated (stretching and bending-dominated) structure. Also, the results obtained by this theory agree well with the FEM results.
