ЩО FATIGUE LIMIT ОЗНАЧАЄ У АНГЛІЙСЬКА?
Межа втоми
Межа втоми, межа витривалості та усталену міцність - це всі вирази, що використовуються для опису властивостей матеріалів: амплітуда циклічного стресу, яка може бути застосована до матеріалу, не викликаючи втоми. Сплави чорних сплавів і титанових сплавів мають чітко виражену межу, амплітуду, нижче якої, як видається, немає кількості циклів, які можуть спричинити провал. Інші структурні метали, такі як алюміній та мідь, не мають чіткої межі і в кінцевому підсумку зазнають невдач навіть з невеликої амплітуди напруги. У цих випадках для виявлення втомного життя матеріалу обрано кілька циклів.
Визначення fatigue limit у англійська словнику
Визначення терміну "втома" у словнику - це максимальний стрес, який може бути викликаний матеріалом або його частиною без розтріскування або розриву.
