摘要
木文研究了间接直流电位法(IDC法)和交流电位法(AC法)用于监测疲劳短裂纹扩展速率的有关技术问题。文中提出了一种用电磁场边界元法对电位法进行标定的理论标定方法。研究了有关的试验标定方法。并对IDC法和AC法的适用范围、灵敏度和稳定性等做了详细的比较分析。
The technique of measurement of growth, rate of fatigue short crack with indirect KC (IDC) potential system and AC potential system was investigated. A theoretical calibration method for potential system with electric field boun dary element method was introduced. The experimental calibration methods for potential system were studied. The sensitivity, stability and applicable range of IDC system and AC system were analysed and compared.
