摘要
应用ANSYS软件对平板中心裂纹构件的应力分布进行有限元分析,不仅得出了符合积分理论解的精度较高的 分析结果,并且通过对加载构件表面漏磁场的测量,验证了应力集中与磁记忆效应之间的规律,进一步探讨了磁记忆 检测在铁磁构件损伤预诊断中应用的可行性。
Stress distribution of flat plate, which has a crack in center, was analyzed in terms of finite element method by ANSYS software. The results agreed with theoretical calculation of integration, and some regulations between stress concentration and magnetic memory effect are proved through measuring magnetic leakage field of flat plate. The applicability of magnetic memory testing in pre-diagnosis of ferromagnetism items was discussed.
