fatigue crack initiation (english) - meaning, definition, translation, pronunciation


Part of Speech

Phonetic Transcription

Meaning and Usage

Fatigue crack initiation refers to the process by which micro-cracks begin to form in a material due to repeated stress and strain over time. This phenomenon is particularly significant in engineering and materials science, as it can lead to failure in structural components, especially those subjected to cyclic loading.

It is a technical term commonly used in written contexts, such as research papers, engineering reports, and technical documentation. It is less frequently used in everyday oral speech but is crucial in discussions concerning material performance, safety assessments, and failure analysis.

Example Sentences

  1. The researcher focused on the fatigue crack initiation in aluminum alloys exposed to cyclic loads.
  2. Исследователь сосредоточился на инициации усталостных трещин в алюминиевых сплавах, подвергнутых циклическим нагрузкам.

  3. Understanding the mechanics of fatigue crack initiation can help engineers design safer structures.

  4. Понимание механики инициации усталостных трещин может помочь инженерам разрабатывать более безопасные конструкции.

  5. The study aims to evaluate how different environmental conditions affect fatigue crack initiation in composite materials.

  6. Исследование направлено на оценку того, как условия окружающей среды влияют на инициацию усталостных трещин в композитных материалах.

Idiomatic Expressions

While "fatigue crack initiation" itself may not appear in idiomatic expressions, it is related to several engineering terms that deal with failure and fracture mechanics. Here are some expressions related to the concept:

  1. In the crack of dawn – While not directly related to fatigue cracks, this expression refers to early morning, symbolizing a time when things might be fresh and unbroken, contrasting with the concept of structural failure.
  2. В небе раннего утра всё ещё образуется еще больше трещин, в отличие от тех, что были с самого начала.
    (In the early morning sky, more cracks are still forming, unlike those that existed from the start.)

  3. Hit a wall – This expression usually refers to reaching a point where progress stops, similar to materials reaching their limit under stress.

  4. Когда проект дошёл до трещин в результате усталости, мы поняли, что попали в тупик.
    (When the project reached cracks due to fatigue, we realized we hit a wall.)

  5. Break the mold – Though it generally refers to unique creations or ideas, it can metaphorically relate to the breaking of structural integrity.

  6. Инновационный дизайн смогла разрушить форму, минимизируя риски инициации усталостных трещин.
    (The innovative design managed to break the mold, minimizing the risks of fatigue crack initiation.)

Etymology

The term is derived from two words: - "Fatigue," from Middle French "fatigue" meaning weariness (which came from Latin "fatigare"). - "Crack," from Old English "cracian," meaning to break or snap. - "Initiation," from Latin "initiare," meaning to begin or start.
