TL;DR: The performance of finite element methods for dynamic crack propagation in brittle materials is studied in this paper, where three methods are considered: the extended finite element method (XFEM), element deletion method and interelement crack method.
Abstract: The performance of finite element methods for dynamic crack propagation in brittle materials is studied. Three methods are considered: the extended finite element method (XFEM), element deletion method and interelement crack method. The extended finite element method is a method for arbitrary crack propagation without remeshing. In element deletion methods, elements that meet a fracture criterion are deleted. In interelement crack methods, the crack is limited to element edges; the separation of these edges is governed by a cohesive law. We show that XFEM and interelement method show similar crack speeds and crack paths. However, both fail to predict a benchmark experiment without adjustment of the energy release rate. The element deletion method performs very poorly for the refinements studied, and is unable to predict crack branching.

TL;DR: In this article, a new method, Applied Element Method (AEM) for analysis of structures is introduced, where the structure is modeled as an assembly of distinct elements made by dividing the structural elements virtually.
Abstract: A new method, Applied Element Method (AEM) for analysis of structures is introduced. The structure is modeled as an assembly of distinct elements made by dividing the structural elements virtually. These elements are connected by distributed springs in both normal and tangential directions. We introduce a new method by which the total behavior of structures can be accurately simulated with reasonable CPU time. This paper deals with the formulations used for linear elastic structures in small deformation range and for consideration of the effects of Poisson's ratio. Comparing with theoretical results, it is proved that the new method is an efficient tool to follow mechanical behavior of structures in elastic conditions.

TL;DR: In this article, a nonlinear, discrete crack, interface and finite element approach was used to predict the bond-slip behavior of a reinforced concrete reinforcement bar embedded in concrete.
Abstract: A new approach is taken to predict numerically the bond‐slip behavior of a reinforcing bar embedded in concrete. Attention is focused on radial, secondary cracking. This cracking is found not to follow the principles of linear elastic fracture mechanics, and therefore is modeled using a nonlinear, discrete crack, interface and finite element approach. A new method for finite element modeling of nonlinear fracture is presented. A “tension‐softening element” is introduced for the purpose of modeling bond‐slip in practical reinforced concrete engineering problems. Finally, as an example, a reinforced concrete tension diaphragm is analyzed.
