GEOMETRY EFFECT OF INDENTERS ON DYNAMIC HARDNESS
Abstract
The present paper reports on the underlying concept for securing the measuring basis used in the method of dynamic hardness. The dynamic hardness was evaluated from measurements of residual contact dimensions as a function of impact velocity and continuous force - displacement curves over the velocity range 5 to 40 m s<sup>-1</sup> for various geometry of indenters. The value for several engineering metals obtained dynamic hardness was 1.12 - 1.40 higher than the static hardness. The higher hardness in impact causes more extensive elastic recovery and smaller plastic zone surrounding the contact site.
