Abstract

To improve the accuracy of predicting multiaxial fatigue life, an enhanced multiaxial low-cycle fatigue life model is proposed based on the FS model. This model introduces a correction parameter for the stress-related term to consider the influence of normal stress and shear stress on the critical plane. The feasibility of the model is investigated, and it is validated using fatigue test data from eight different materials. The results indicate that the proposed model is applicable for both symmetric and asymmetric loading conditions under constant amplitude loading, with highly accurate fatigue life prediction results.

增强型多轴低循环疲劳寿命模型

为了提高多轴疲劳寿命预测的准确性，在 FS 模型的基础上提出了一种增强型多轴低循环疲劳寿命模型。该模型为应力相关项引入了一个修正参数，以考虑法向应力和剪切应力对临界面的影响。研究了该模型的可行性，并使用八种不同材料的疲劳测试数据对其进行了验证。结果表明，所提出的模型适用于恒定振幅加载下的对称和非对称加载条件，其疲劳寿命预测结果非常准确。

期刊介绍： Mechanics Research Communications publishes, as rapidly as possible, peer-reviewed manuscripts of high standards but restricted length. It aims to provide: • a fast means of communication • an exchange of ideas among workers in mechanics • an effective method of bringing new results quickly to the public • an informal vehicle for the discussion • of ideas that may still be in the formative stages The field of Mechanics will be understood to encompass the behavior of continua, fluids, solids, particles and their mixtures. Submissions must contain a strong, novel contribution to the field of mechanics, and ideally should be focused on current issues in the field involving theoretical, experimental and/or applied research, preferably within the broad expertise encompassed by the Board of Associate Editors. Deviations from these areas should be discussed in advance with the Editor-in-Chief.
