HIGHLIGHTS
- who: Thomas Menouillard and colleagues from the LaboratoireBatJean d'Alembert, , rue des Sciences , Villeurbanne, France have published the article: Efficient explicit time stepping for the extended finite element method (X-FEM), in the Journal: (JOURNAL)
- what: The authors show that if one uses this technique the critical time step does not tend to zero as the support of the discontinuity reaches the boundaries of the elements. In the present paper, a mass matrix lumping technique is proposed for enriched functions. The aim of this section is to construct a lumped mass matrix which enables one . . .
