计算机控制测定门坎值的新方法

New Method of Determinning the Threshold Value by Computer Control

    摘要
  • 摘要: 阐述了用新型AMSLER高频疲劳试验机,结合计算机控制测定材料门槛值△Kth的新方法.该方法通过在恒应力比R下疲劳一定周次后,频率下降不超过某一特定值,从而得到门槛值△Kth.

     

    Abstract: A new method of determinning the threshold value △Kth on a new type AMSLER fatigue test system by computer control is given. By using this method, △Kth can be obtained after the material has been fatigued a given cycles under constant stress ratio R, on condition that the decreasing of frequency is less than a certain value.
