N2 - Hertzian ring crack initiation was studied in several brittle materials using spherical indenters made from different materials. Target materials included silicon carbide, silicon nitride, and borosilicate glass. Indenter materials included glass, zirconia, steel, silicon nitride, alumina, and tungsten carbide. Decreasing the elastic modulus of the indenter against every one of the target materials resulted in the target material exhibiting ring crack initiation at lower forces. The trend is consistent and conclusive. This response is described in regards to the Poisson's mismatch between indenter and target and the associated friction effects that it produces.
