WebSep 9, 2016 · zxtanφ, where φ is the centerline-to-face angle of the indenter [28]. Here the diamond indenter is assumed to be incompressible and, therefore, the two stress components are always proportional to each other, which is a good approximation for most materials, including those with strengths comparable to that of cubic diamond [29, 30]. …
