Abstract

A numerical model within the framework of the nonsymmetric formulation of the strong discontinuityapproach(SDA)forfracturesimulationsisinvestigated. Shortcomingsofthebasicformulations are analyzed and potential methods to overcome them are discussed. A new tracking algorithm intending to enforce continuity of the crack is proposed. The proposed model is applied to simulations of academic and large-scale problems.
