鋼球の衝撃によるIndentationについで

抄録

In order to obtain the relations between the indentations and the conditions of impact as the basis for shot peening, flat piece of steel was clamped to a large solid block and shot by hard steel ball.
The result obtained is expressed by equations (1) (5) in the paper with the following nomenclature : d, h, V=chordal diameter, depth and volume of indentation, D, v=diameter and velocity of steel ball, k_d, k_h, k_v =material constant.
Force of impact is connected to the equivalent static pressure (P) from the chordal diameter of indentations penetrated by the method above mentioned and static loading by the Vickers hardness testisting machine.
