• A rigid-plastic analysis of an assembly of regularly arranged circular elements with an equal diameter was made to consider the relationship between the micro- and macro-mechanisms of cohesive granular materials. No elastic constant for elements was employed whereas rolling and plastic sliding at the contact points was considered. The equations of equilibrium of elements at the critical state were solved by using the linear programming method to minimize the upper bound of the applied force. Some of the deformation modes were compared with the results of an experiment where a set of coins are used. It was found that the applied force at critical state can be obtained in a quasiclosed form by considering the condition of equilibrium of the whole assembly. Finally the global cohesion is related with the local one in a simple way when the number of elements are increasing.
