Abstract

In this paper, the fictitious crack model is employed together with the Dual Boundary Element Method to simulate the pure mode I and mixed mode crack propagation in concrete. An important feature of the method is that, no interior remeshing is required to model the crack growth. The numerical simulations is controlled through the crack length as a mono- tonic increasing function during the fracture process. Under the crack length controlled scheme, the snapback instability is observed in the mixed mode problem. 1 Introduction The fictitious crack model (also called cohesive crack model) is one of the com- monly used methods for crack propagation in concrete or material-like concr
