If tangents are drawn to the ball at the impression edges for d/d = 0. 75, they meet below the center of the impression at an angle of 6°, the angle chosen for the Vick-ers indenter. use of diamond allowed the Vickers test to be used to evaluate any material (except diamond) and, furthermore, had the very important advantage
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]. … WebApr 7, 2012 · As the diamond indenter is treated as a rigid body, the C–C interactions between indenter atoms are ignored. The indenter is initially positioned above the substrate. The MD simulations of nanoindentation consist of relaxation and indentation stages. After relaxation, the indentation is modeled by moving the indenter downwards …
