To address the indeterminacy of contacts involving nonconvex angles of arbitrarily shaped polyhedron, an easy-to-implement local convex decomposition method(LCD), dividing any arbitrary angle along the extensive plane angle of concave dihedral angles into a set of convex angles, was proposed and employed to extend the entrance plane method(EPM). The LCD-EPM is a universal method for contact detection of general polyhedrons, and herein, enabled the use of a three-dimensional discontinuous deformation analysis (3-D DDA) to calculate contacts between general polyhedrons. Finally, the extended 3-D DDA program was used to illustrate the powerful ability of LCD including contact detection and calculation as well as an impact-contact behaviour analysis of general polyhedrons, which validates the correctness and robustness of the LCD-EPM. The extended 3-D DDA program can be applied in mechanical analyse of complex polyhedral block systems.
