A method is introduced for extracting tensorial stress measures from rigid-body-spring networks with random geometry. Stress analysis of a uniformly stretched material indicates that rigid-bodyspring networks can be made elastically homogeneous provided two basic conditions are met: 1) network geometry is defined by a Voronoi diagram, and 2) the network degrees of freedom are defined at the Voronoi cell nuclei. For more general loadings, accuracy of the stress retrieval algorithm is
