英文摘要Discontinuous deformation analysis (DDA) method is a newly developed discrete element method which employs the implicit time-integration scheme to solve the governing equations and the open-close iteration (OCI) method to deal with contact problem, its computational efficiency is relatively low. However, spherical element based discontinuous deformation analysis (SDDA), which uses very simple contact type like point-to-point contact, has higher calculation speed. In the framework of SDDA, this paper presents a very simple contact calculation approach by removing the OCI scheme and by adopting the maximal displacement increment (MDI). Through some verification examples, it is proved that the proposed method is correct and effective, and a higher computational efficiency is obtained.
