摘要

针对316L不锈钢开展一系列多轴低周疲劳试验,该材料显现出了较为显著的非比例附加强化特性;基于四种应变法模型进行疲劳寿命预测,结果显示:ASME等效应变模型、Itoh模型均无法有效反映非比例附加强化对寿命的影响,前者预测结果偏于危险,后者预测结果趋于保守,而与临界平面法结合的Fatemi-Socie模型、Susmel模型预测结果则较好。为便于应用,针对ASME等效应变模型的不足,对等效应变中的塑性项进行修正,使其可更有效的反映非比例加载路径对寿命的影响,发展一种优于一般修正方法的实用方法,采用包括316L不锈钢在内的六种材料的多轴疲劳试验数据对其进行了验证。

Abstract

A series of multiaxial low-cycle fatigue texts were conducted on 316 L stainless steel. Additional hardening was clearly observed under non-proportional loading. Then four strain-based models were utilized for life prediction. The result show that the ASME model and Itoh model could not properly reflect the effect of non-proportional hardening on fatigue life,the ASME model tended to overestimate fatigue life,while the Itoh model contrary to ASME model. Fatemi-Socie model and Susmel model,which both based on critical plane approach,presented better prediction results. In order to overcome the deficiency of ASME model,a practical life prediction model for multiaxial low-cycle fatigue is proposed by means of modifying the plastic term of ASME equivalent strain. Evaluated by utilizing experimental data of six materials including 316 L stainless steel,the proposed model have a higher accuracy than similar models established through modifying ASME model.
