Resumen
El level set method es una técnica que se utiliza habitualmente para describir matemáticamente la propagación de superficies mediante la aproximación y resolución de ecuaciones diferenciales. Esta técnica ha sido ampliamente utilizada en combinación con el XFEM, especialmente en el análisis del crecimento de grietas. Sin embargo, existen otras opciones que se basan en consideraciones geometricas como el fast marching method. En este trabajo se implementa una técnica geométrica basada en el fast marching method y level sets para la descripción de propagación de grietas en XFEM y, por tanto, compatible para su uso directo con esta técnica en cálculos de mecánica de la fractura.
