Tutorial on Hertz Contact Stress - University of Arizona
wp.optics.arizona.eduThe stresses and deflections arising from the contact between two elastic solids have practical application in hardness testing, wear and impact damage of engineering ceramics, the design of dental prostheses, gear teeth (Fig. 6), and ball and roller bearings (Fig. 7). For optomechanics,

dot.ca.govtherefore, the preferred means of specifying the elastomer. Hardness has been widely used in the past because the test for it is quick and simple. However, the results obtained from it are variable and correlate only loosely with shear modulus.” 1. The shear modulus of elastomer, obtained from testing, is approximately 100 psi at

Although this result is of considerable interest in research, the practical use is rather limited. The work hardening capability of the material depends on the tribological system; this sometimes gives startling results and
