IPC: G01L1/00
Filed: 2010-06-02
Abstract: PROBLEM TO BE SOLVED: To precisely measure residual stress and distribution thereof in a shallow surface layer even when an object is made of a material of coarse crystal grains.SOLUTION: A test piece 5 is cut off from the surface of a dovetail of a turbine blade, and a measurement plane 5a, which is a part of the dovetail, is polished in a layered state in order. Strain on a rear face 5b is measured with the output by a strain gauge 7 attached to the rear face 5b of the test piece 5 opposite to the measurement plane 5a. A strain having the same value of this strain is reproduced using an analytical model. In particular, in the analytical model which has the same dimensions and the same material as those of the test piece 5, temperature or linear expansion coefficient is determined for each layer, which is formed by removing in a layered state at the measurement plane side of the analytical model so as to coincide with the strain changes measured on the test piece 5. Stress distribution is obtained from the analytical model each layer of which is set with determined temperature or linear expansion coefficient and is determined as the distribution of residual stress in a depth direction generated on the measurement plane 5a of the test piece 5.
