Abstract

A 3D lattice model is used to predict the elastic behaviour of homogeneous or het- erogeneous materials. In this paper, for the heterogeneous case, it is shown that such a model gives the same results as the analytical model proposed by Hashin and Shtrikman. These results are also compared with one set of experiments. 1 Introduction In lattice models the material is schematized as a network of truss or beam ele- ments connected at the extremities. Truss lattices were used already as early as 1940 [1] for simulating problems of elasticity. In physics such models are inten- sively used to study percolation problems and electrical conductivity in materials,
