Abstract

An equivalent damage model was established to study the fatigue damage behavior of steel-aluminum friction stir welding (FSW) joints. Internal defects of friction stir welding joint under various cyclic loading stages were observed by X-ray microcomputed tomography (X-CT). For the characteristics of defects of the steel-aluminum FSW joints, a simplified method of defects considering key parameters is proposed and then the defect model is established. The FSW joint model was established based on the steel-aluminum boundary contour identified by using image processing techniques. Based on the defect model and the FSW joint model, the equivalent damage model was developed. The equivalent damage model was subjected to finite element analysis and compared with the test using the strain amplitude as the damage variable. The equivalent damage model can be used to assess fatigue damage in steel-aluminum FSW joints, which provides some theoretical basis for fatigue life prediction.

基于等效损伤模型的钢铝搅拌摩擦焊接头疲劳损伤研究
建立了钢铝搅拌摩擦焊(FSW)接头的等效损伤模型,研究了FSW接头的疲劳损伤行为。利用X射线微计算机断层扫描(X-CT)对搅拌摩擦焊接接头在不同循环加载阶段的内部缺陷进行了观察。针对钢铝FSW节点缺陷的特点,提出了一种考虑关键参数的缺陷简化方法,并建立了缺陷模型。基于图像处理技术识别出的钢铝边界轮廓,建立了FSW接头模型。在缺陷模型和FSW节点模型的基础上,建立了等效损伤模型。对等效损伤模型进行了有限元分析,并与以应变幅度为损伤变量的试验进行了比较。等效损伤模型可用于评估钢铝FSW接头的疲劳损伤,为疲劳寿命预测提供了一定的理论依据。
