Zusammenfassung

El principal objetivo de este trabajo es estudiar dos relevantes montajes experimentales diseñados para estudiar la rotura a cortante y comprobar si permiten estudiar la evolución de la fractura en Modo II y no sólo inducir una rotura por cortante al comienzo del proceso de fractura. Se han empleado dos ensayos, un ensayo estandarizado descrito en la normativa japonesa, referido aquí como JSCE, y el ensayo de push-off. Los ensayos se han realizado sobre probetas de yeso reforzado con fibras, empleando varias proporciones de fibras de polipropileno y se han monitorizado mediante correlación digital de imágenes (DIC). Los resultados muestran que es relativamente sencillo inducir una rotura en modo II con ambos ensayos pero, una vez se inicia la fractura, es extremadamente difícil lograr una evolución del proceso de fractura en condiciones de Modo II. En general, el Modo II tiene una fuerte influencia en el comienzo de la fractura, pero posteriormente el Modo I predomina.
