Numerical Study of Two-Dimensional Fracture Problems with X-FEM

Abstract

The fundamental concept and formula of X-FEM were introduced in Chapter 4. Based on the program developed by the authors and colleagues, numerical studies of two-dimensional fracture problems are given in this chapter to further demonstrate the capability and efficiency of the algorithms and programs of X-FEM in applications of strong and weak discontinuity problems.
