Abstract
1. Способ определения остаточных напряжений по характеристикам твердости материала, заключающийся в том, что уровень остаточных напряжений в локальных зонах на поверхности изделия оценивают по изменению регистрируемых значений твердости металла в этих зонах относительно исходных значений. ! 2. Способ по п.1, отличающийся тем, что в локальных зонах на поверхности изделия делают параллельные надрезы, ориентированные под углом 90° по отношению друг к другу, так, чтобы геометрические оси надрезов совпадали с наиболее вероятным направлением действия главных напряжений. 1. The method of determining residual stresses according to the characteristics of the hardness of the material, which consists in the fact that the level of residual stresses in local zones on the surface of the product is estimated by the change in the recorded values of the hardness of the metal in these zones relative to the initial values. ! 2. The method according to claim 1, characterized in that in local areas on the surface of the product make parallel cuts oriented at an angle of 90 ° with respect to each other, so that the geometric axis of the cuts coincide with the most probable direction of action of the main stresses.
