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.

另外，节理单元有实际的厚度，可以根据实际节理的性质确定计算参数，这一点也体现出了对刚性块体离散元方法的改进。

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.

引入零长度刚性元模拟多个刚体元汇交于一点和相邻刚体元轴线不在一直线上等情形。

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.
