A stable XFEM formulation for multi-phase problems enforcing the accuracy of the fluxes through Lagrange multipliers Díez, Pedro; Cottereau, Régis; Zlotnik, Sergio (2013-11-02)
Open AccessWhen applied to diffusion problems in a multi-phase setup, the popular extended finite element method (XFEM) strategy suffers from an inaccurate representation of the local fluxes in the vicinity of the interface. The XFEM ...

Restricted access - publisher's policyWe present an r-adaptivity approach for boundary value problems with randomly fluctuating material parameters solved through the Monte Carlo or stochastic collocation methods. This approach tailors a specific mesh for each ...
