Evaluation of fracture toughness of small volumes by means of cube-corner nanoindentation Cuadrado Lafoz, Nuria Casellas Padró, Daniel Anglada Gomila, Marcos Juan Jiménez Piqué, Emilio Àrees temàtiques de la UPC::Enginyeria dels materials Strength of materials Fracture mechanics Resistència de materials Mecànica de fractura In this work, the applicability of the two most commonly used equations for calculating the fracture toughness by nanoindentation is discussed in terms of the indenter geometry and the indentation crack morphology. These equations are calibrated for Berkovich and cube-corner indenters taking into account the actual indentation crack morphology, aimed at attaining a more reliable estimation of fracture toughness in small material volumes by nanoindentation.
