Elementos finitos de alto orden para problemas con interfaces materiales

Abstract

La solució de problemes amb intefícies materials és en l'actualitat un problema de gran interés. El mètode eXtended Finite Elements permet resoldre aquests tipus de problemes sense necessitat d'una malla que s'adapti a la interfície. El problema és el mal condicionament quan un element és dividit per la interfície en una regió molt més gran que l'altre. L'objectiu d'aquest treball és proposar algoritmes per modificar la malla evitant elements mal condicionats en el context d'aproximacions d'alt ordre.
