Estudio de la morfologia de grietas generadas por nanoindentación y su efecto en el cálculo de la tenacidad de fractura

Abstract

En el presente trabajo se ha utilizado la técnica de nanoindentación para inducir grietas en diferentes materiales cerámicos y estudiar la morfología de grieta generada por la aplicación de un indentador tipo Berkovich . El estudio morfológico de las grietas se ha llevado a cabo medi ante pulido secuencial y la técnica de microscopía de haz de iones focalizados (FIB/SEM). Para la geometría de indentador utilizada y la morfología de grieta obtenida, se ha llevado a cabo un estudio de la aplicabilidad de las expresiones más comúnmente utilizadas para el cálcu lo de la tenacidad de fractura en materiales frágiles por i ndentación. Previamente al estudio de la validez de las ecuaciones, para poder obtener una medida de K c fiable, se ha realizado una calibración de la s ecuaciones para la geomet ría de indentador tipo Berkovich
