DETERMINATION OF RESIDUAL STRESSES BY ETCHING CANTILEVERED SAMPLE

The article describes experimental-theoretical method of determining technological sur- face residual stresses with application of layer-by-layer etching of the cantilever-fixed sample. The developed method of calculation of residual stresses in the surface layers of the material. It is shown that the proposed calculation method is more sensitive compared to the known and practically coincides with the classic, which uses sample with two simply supported edges.
