The computer program BALL has been used for the past several years to model and study the behavior of two – dimensional assemblies of discs. The main result of the study thus far, a qualitative description of the material behavior, is discussed. An attempt has been made to introduce measures that may be used in a future constitutive model. The main measures, a partitioned stress tensor, and a constraint ratio, which is related to the stability of the assembly, are introduced and illustrated for some numerical experiments with BALL.
