Discontinuous deformation analysis (DDA) by Shi is an alternative to the commonly used discontinuity based discrete element method. The author discovered that there are some problems in both the theory and the actual implementation of this method. In this paper, the author will discuss some modifications and improvements to the original method so that the problems of DDA can be overcome and it can become a practical tool for general types of problems. DDA is also applied to a classical problem in continuum and compare with UDEC and classical solution to demonstrate the applicability of this method towards general problems.
