On the construction of approximation space to model discontinuities and cracks with linear and quadratic extended finite elements
Abstract This paper presents a robust enrichment strategy to model weak and strong discontinuities as well as cracks for industrial applications. First, numerical issues encountered with popular extended finite element approximation spaces are pointed out. Then, the paper gives indications on how to...
