Abstract

Micromechanical fatigue lifetime predictions, in particular for the high cycle fatigue regime, require an appropriate modelling of mean stress effects in order to account for lifetime reducing positive mean stresses. Focus of this micromechanical study is the comparison of three selected fatigue indicator parameters (FIPs), with respect to their applicability to different total strain ratios. In this work, investigations are performed on the modelling and prediction of the fatigue crack initiation life of the martensitic high-strength steel SAE 4150 for two different total strain ratios. First, multiple martensitic statistical volume elements (SVEs) are generated by multiscale Voronoi tessellations. Micromechanical fatigue simulations are then performed on these SVEs by means of a crystal plasticity model to obtain microstructure dependent fatigue responses. In order to account for the material specific fatigue damage zone, a non-local homogenisation scheme for the FIPs is introduced for lath martensitic microstructures. The numerical results of the different non-local FIPs are compared with experimental fatigue crack initiation results for two different total strain ratios. It is concluded that the multiaxial fatigue criteria proposed by Fatemi-Socie is superior for predicting fatigue crack initiation life to the energy dissipation criteria and the accumulated plastic slip criteria for the investigated total strain ratios.

摘要

微机械疲劳寿命预测，特别是对于高周疲劳情况，需要对平均应力效应进行适当建模，以便考虑会缩短寿命的正平均应力。这项微机械研究的重点是比较三个选定的疲劳指标参数（FIPs）在不同总应变比下的适用性。在这项工作中，针对两种不同的总应变比，对马氏体高强度钢SAE 4150的疲劳裂纹萌生寿命进行了建模和预测研究。首先，通过多尺度Voronoi镶嵌生成多个马氏体统计体积单元（SVEs）。然后利用晶体塑性模型对这些SVEs进行微机械疲劳模拟，以获得与微观结构相关的疲劳响应。为了考虑材料特定的疲劳损伤区域，针对板条马氏体微观结构引入了一种用于FIPs的非局部均匀化方案。将不同非局部FIPs的数值结果与两种不同总应变比下的实验疲劳裂纹萌生结果进行了比较。得出的结论是，对于所研究的总应变比，Fatemi-Socie提出的多轴疲劳准则在预测疲劳裂纹萌生寿命方面优于能量耗散准则和累积塑性滑移准则。
