3 unusual facts about Discontinuous Deformation Analysis


Discontinuous Deformation Analysis

Recent progress in DDA algorithm is reported by Kim et al. and Jing et al. which is a coupling of fluid flow in fractures.

An example of this approach is the research by Chang et al. and also Jing who resolved this problem by adding finite element meshes in the two-dimensional domain of the blocks so that stress variations within the blocks can be allowed.

The DDA contact model which was originally based on penalty method was improved by adopting the Lagrange type approach reported by Lin et al.
