- Additional information
- This work is a result of a collaboration initiated by Agathos with Prof. Chatzi at ETH Zurich (chatzi@ibk.baug.ethz.ch) . It remedies a known problem of the extended/generalized finite element method, enabling its application to large three-dimensional crack propagation problems in a minimally intrusive way. Recently, the approach was built upon to develop a method for generalized isogeometric analysis. Results from this work helped to secure a H2020 Marie Curie IF (Contract No. 795917, EUR 175,0000) for Agathos.
