XFEM based fictitious domain method for linear elasticity model with crack

Autor: Bodart, Olivier, Cayol, Valérie, Court, Sébastien, Koko, Jonas

Reduction of computational cost of solutions is a key issue to crack identification or crack propagation problems. One of the solution is to avoid re-meshing the domain when the crack position changes or when the crack extends. To avoid re-meshing, w

International audience; Among the clustering methods, K-Means and variants are very popular. Thesemethods solve at each iteration the first order optimality conditions. However, in somecases, the function to be minimized is not convex, as for the Fuz
