Summary
The status and some recent developments of continuum modeling for large repetitive lattice structures are summarized. Discussion focuses on a number of aspects including definition of an effective substitute continuum; characterization of the continuum model; and the different approaches for the generation of the properties of the continuum, namely, the constitutive matrix, the matrix of mass densities, and the matrix of thermal coefficients. Also, a simple approach is presented which can be used to generate analytic expressions and/or numerical values of the continuum properties.
Application of the proposed approach to some beamlike and double-layered platelike lattices, currently considered as candidates of large space structures, is described. Future directions of research on continuum modeling are identified. These include needed extensions and applications of continuum modeling as well as computational strategies and modeling techniques.
