Variational Extended Finite Element Model for Cohesive Cracks: Influence of Integration and Interface Law

  • Conference paper

Part of the book series: IUTAM Bookseries ((IUTAMBOOK,volume 5))

Summary

According to a recently proposed variational formulation of the Extended Finite Element Method for cohesive crack propagation analyses [1] the length and the direction of new crack segments are determined on a global level from minimizing the total energy of the system. The focus of this paper is laid on the influence of the numerical integration and of the cohesive interface law on the energy distribution and, consequently, on the predicted crack trajectory. These influences are investigated by means of crack propagation analyses in plane structures made of quasi-brittle materials.
