Abstract <p>An analytical model for predicting elastic properties and strength of braided lattice structures using micromechanics of materials is developed: it involves dividing the representative volume element into several subelements in such a way that their combination can be considered as a multilayer laminate-type composite. Mechanical properties of laminates are determined without assuming iso-strain, but based on constant in-plane strain with constant out-of-plane stress. The nonlinear mechanical behavior of a balanced plain-weave composite is studied in the context of the inelastic properties of the polymer matrix. The accuracy of the model is verified by experimental studies.</p>
