Abstract
Изобретение относитс к механическим испытани м. Цель изобретени - повышение точности определени максимальной долговечности конструкции за счет приближени конструкции к равнопрочной. Конструкцию нагружают циклически. Определ ют зоны с максимальным отношением напр жени к пределу ограниченной выносливости . Прерывают испытание и подвергают эти зоны технологической обработке, снижающей дефектность материала, возобновл ют нагружение, определ долговечность конструкции.The invention relates to mechanical tests. The purpose of the invention is to improve the accuracy of determining the maximum durability of a structure by bringing the structure closer to an equal strength. The design is loaded cyclically. Zones with a maximum ratio of stress to limited endurance are determined. The test is interrupted and these zones are subjected to a technological treatment that reduces the defectiveness of the material, resume loading, determine the durability of the structure.
