Applying the Newmark Method to the Discontinuous Deformation Analysis
Discontinuous deformation analysis (DDA) is a newly developed simulation method for discontinuous systems. It was designed to simulate systems with arbitrary shaped blocks with high efficiency while providing accurate solutions for energy dissipation. But DDA usually exhibits damping effects that …

A new method of meshing in discontinuous deformation analysis (DDA)
Discontinuous Deformation Analysis (DDA) is a discrete element method developed by Shi [1988] specifically for modelling blocky rock masses. The DDA method is based on the assumption that deformation and failure of such rock masses is primarily due to differential movements of rock blocks, rather …
