摘要
介绍了用直流电位法测量疲劳裂纹长度方法的基本原理、实现方法及所需配置的仪器,并对有关影响因素作了分析。该测量系统主要用于高温下的各种材料在恒幅载荷下的疲劳裂纹扩展和门槛值试验中的疲劳裂纹长度的测量,可提高测量疲劳裂纹长度的自动化水平。
A measurement method for crack length is described in this paper, Based on this method, fatigue crack growth lenglh under constant ampliftude loading and crack length of threshold behavior all can be determined at high temperature. Automatic level of measurement crack length is improved.
