SUMMARYA technique for modelling of arbitrary three-dimensional dynamically propagating cracks in elastic bodies by the Element-Free Galerkin (EFG) method with explicit time integration is described. The meshless character of this approach expedites the description of the evolving discrete model; in contrast to the ÿnite element method no remeshing of the domain is required. The crack surface is deÿned by a set of triangular elements. Techniques for updating the surface description are reported. The paper concludes with several examples: a simulation of mixed-mode growth of a center crack, mode-I surface-breaking penny-shaped crack, penny-shaped crack growing under mixed-mode conditions in a cube, and a bar with centre through crack.

“…Saleh and Aliabadi [29] validated their numerical model by taking f t = 2.8 -MPa and G F = 100 N/m. Xie and Gerstle [24] for the same set of tests took: f t = 4.0 MPa and G F = 150 N/m; obviously, the concrete fracture parameters are quite different. A relatively small number of beams were tested in each series.…”

“…The cohesive crack model, developed by Hillerborg and co-authors [1] for mode I fracture of concrete, was shown to be efficient to model the fracture process of quasi-brittle materials. It has been extended to mixed mode fracture (modes I and II) and incorporated into finite element programs [23][24][25][26][27][28] and into boundary element codes [29]. One of the difficulties associated with these programs is that they require the remeshing and/or refinement of the finite element mesh when the crack grows, and some of them also require an input of material properties that are difficult to evaluate.…”

This paper presents a numerical implementation of the cohesive crack model for the anal-ysis of quasibrittle materials based on the strong discontinuity approach in the framework of the finite element method. A simple central force model is used for the stress versus crack opening curve. The additional degrees of freedom defining the crack opening are determined at the crack level, thus avoiding the need for performing a static condensation at the element level. The need for a tracking algorithm is avoided by using a consistent procedure for the selection of the separated nodes. Such a model is then implemented into a commercial program by means of a user subroutine, consequently being contrasted with the experimental results. The model takes into account the anisotropy of the material. Numerical simulations of well-known experiments are presented to show the ability of the proposed model to simulate the fracture of quasibrittle materials such as mortar, con-crete and masonry.

“…the finite element method (FEM), the boundary element method (BEM) and two more recent numerical approaches: meshless methods and extended FE methods. Since the FEM was first used to model crack propagation in reinforced concrete beams by Ngo and Scordelis [1], it has been the predominant numerical method for crack problems [2][3][4]. However, crack propagation modelling with the FEM is still a challenging subject, because it usually requires both fine crack tip meshes [5][6] and sophisticated remeshing algorithms during crack propagation [7][8] to accurately calculate fracture parameters such as stress intensity factors (SIFs).…”
