摘要
疲劳能量理论经历了机械能耗研究和能量耗散研究两个主要阶段。前一阶段主要提出基于机械能耗的疲劳失效判据 ,后一阶段着重研究疲劳过程中的热耗散现象 ,从热力学的角度去解释疲劳问题。
There have two main phases in the development of the fatigue energy, which are mechanical energy phase and energy dissipation phase. The main works of the first phase are to find the fatigue failure criterion based the mechanical energy dissipation. In the second phase, thermal dissipation is studied in detail, and thermodynamics is used to explain the fatigue problems. The main works and conclusions of the fatigue energy theory in the past are briefly reviewed and summarized.
