Abstract

A simulation method has been proposed to estimate the effective elastic moduli of sintered spherical particles by analyzing the response of a random network of springs with 6 degrees of freedom to uniform deformation ; the network is constructed by computer simulation of a 3D random packing of spherical particles, while the spring constants of a pair of sintered particles are estimated by FEM. In order to verify the validity of the proposed method, its 2D version has been applied to an estimation of the effective Young modulus, and its specific procedures have been examined in detail.
