The aim of this paper is to clarify the meaning of the mechanical state variables stress and strain in the case of random granular assemblies. Stress and strain are expressed in terms of local, micro-level variables with the help of two complementary geometrical systems. The two expressions show a strong duality which is also analysed in the paper.
