摘要	The spatial distribution of contact orientations and anisotropy in granular assemblies stand for the directional features of contacts and contact forces. Contact anisotropy and contact force anisotropy are two fundamental concepts for microscopic and macroscopic mechanics of granular materials. In this paper, a kind of diagrammatic description for illustrating anisotropy in granular assemblies, named contact orientation distribution diagram (CODD), is proposed. A group of statistical indicators are developed to determine anisotropies. As a result, contact anisotropies and contact force anisotropies in different granular assemblies which are simulated with different existing methods, under different boundaries and using different densification procedures are compared and discussed.
