Extended finite element method theory and applications pdf
The paper deals with the application of the eXtended Finite Element Method XFEM to simulations of discrete macro-cracks in plain concrete specimens under tension, bending and shear. Fundamental relationships and basic discrete constitutive laws were described. The most important aspects of the numerical implementation were discussed. Advantages and disadvantages of the method were outlined. Planas Fracture and size effect in concrete and other quasi-brittle materials. Lillu J.
Introduces the theory and applications of the extended finite element method ( XFEM) in the linear and nonlinear problems of continua.

Extended Finite Element Method provides an introduction to the extended finite element method XFEM , a novel computational method which has been proposed to solve complex crack propagation problems. The book helps readers understand the method and make effective use of the XFEM code and software plugins now available to model and simulate these complex problems. The book explores the governing equation behind XFEM, including level set method and enrichment shape function. The authors outline a new XFEM algorithm based on the continuum-based shell and consider numerous practical problems, including planar discontinuities, arbitrary crack propagation in shells and dynamic response in 3D composite materials. He has published over papers in leading scientific journals.
