A formula using the indentation fracture technique is given to determine the fracture toughness of ceramic materials. Experimental data are in good agreement with those obtained by the four-point bending technique. The factors that influence K,, are further discussed
## Abstract The main objective of this study was to measure the fracture toughness of the human teeth enamel using the microindentation technique and to compare the results calculated from the equations developed for Palmqvist and radialโmedian cracks. Vickers microhardness measurements of dental c
## Abstract Summary: Based on the results from agglomerateโfree PMMA nanocomposites with 10 and 20 wt.โ% spherical SiO~2~ nanoparticles, it has been shown that indentation fracture mechanics is a straightforward, powerful, costโeffective and timeโeffective tool for analyzing the fracture resistance
