An extensive literature survey of the evolution of the indentation technique is made. The elastic/plastic solution for the spherical cavity expansion is used to obtain a physical explanation for the quantitative measurement of the radial cracks that occur at the indentation impression corners. Finally an expression based on the mentioned theory is given. Experimental data from a series of brittle materials are well fitted by this expression.
