N2 - Multiphase lattice blocks with periodic structure are analyzed by a continuum-based micromechanical approach. As a result, effective stiffness tensors, global initial yield surfaces, global damage thresholds, effective inelastic stress-strain responses and critical yielding temperatures of lattice blocks are established. Applications are given for various types of elastic and inelastic lattice blocks made of an aluminum alloy. Furthermore, a lattice block with negative effective Poisson's ratios is considered, and two types of two-phase lattice blocks that are capable to produce negative effective coefficients of thermal expansion are presented.
