International Classification:

G01N 342
G01N 308

US Classification:

73 81

Abstract:

A device is presented for measuring residual stresses in a solid component. he device includes a hardness measuring component which has an indenter for determining hardness at various locations. Stress (. sigma. ) data is obtained by converting the hardness measurements according to the formula a. multidot. [. sqroot. 4P. sub. o. sup. 2 -3P. sup. 2 -P], where a is a constant in Kbar. sup. -1 mm. sup. 2 /kg, which depends on the type of material under test and also on the type of indentor used, where the pressure p is measured in kg/mm. sup. 2, and where the average pressure p. sub. o is the average value of mean pressure p along a radial cut line of the solid component specimen.
