... Abstract The discontinues deformation analysis (DDA) is a powerful tool to predict and describe the slope failure of fractured rock. An important feature in DDA is the contact detection between different blocks. In this paper first of all a brief introduction on the basic principles of contact...

... straightforward algorithm was developed to detect common area of two convex blocks which have potential of being in "face to face" contact. The possibility of the "face to face" contact pattern is examined by one of the most efficient procedures of contact detection in 3D-DDA, the "Main Plane" method. After...
