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.
