Application of the "fictious crack model" to meshless crack growth simulations

Abstract

In this paper a meshless component is presented, which internally uses the common meshless interpolation technique >Moving Least SquaresFictitious Crack ModelFictitious Crack Model< finite interface elements are included between the crack surface nodes. The determination of the maximum principal strain at the crack tip is done by introducing an influence area around the singularity. On a practical example it is shown that the included elements improve the model by the transmission of the surface forces during monotonic loading and by the representation of the contact forces of closed cracks during reverse loading
