摘要：

The use of Hertzian indentation as a method for determining the fracture toughness of any brittle material is described. The advantage of the method described here is that the only quantity to be measured is a fracture load. Experimental determinations of K-IC for soda-lime glass and high-purity alumina give results 0.71 and 3.72 MPa m(1/2), respectively.
