In addition, the jointed element has certain thickness, so the calculative parameter can be determined by those of the actual joint. It embodies the improvement to rigid block discrete element method.
The zero-length rigid element is introduced to simulate the node at which more elements are jointed together and to treat neighboring elements whose longitudinal axes are not in the same line.

In this paper, a elastic-plastic dynamical constitutive model on jointed rock masses under blasting load is established with the help of the multiple rigid-body dynamics and contact-impact theory.
