Who invented this method?

The article suggests that the method was developed in by Ted Belytschko and collaborators. However, the partition of unity method is described by Babuska and Melenk in a 1997 paper. Is that the origin of XFEM/PUFEM? RuppertsAlgorithm (talk) 13:34, 22 December 2008 (UTC)[reply]

You are absolutely right. Before Belytschko and Co. started publishing on this topic, giving it their own name (XFEM), and making it usable especially for the fracture modeling community, Babuska and Melenk had laid the foundations and the theoretical concept with the Partition of Unity Method. This was already published in 1996 (see, J.M. Melenk and I. Babuska. The partition of unity finite element method: Basic theory and applications. Comput. Methods Appl. Mech. Eng., 139:289–314, 1996). Feel free to improve the article. If you ask me, it should be moved from XFEM to PUM anyway. Tomeasy T C 14:25, 22 December 2008 (UTC)[reply]
