A Development of 3D-DDA with Finite Deformation Theory

Article Preview

Abstract:

A post-adjustment method that makes DDA coupled with finite deformation theory was presented in this paper. The displacement post-adjustment equations were derived. We also calculated two examples to illustrate this method. The method was also compared with original DDA and reference’s. It shows that the method in this paper can work well on the block rotation error problems.
