提出了一种基于裂纹扩展的电阻点焊疲劳寿命估算方法。该方法还考虑了焊接残余应力的影响。它可以提供一个准确的和系统的预测点焊接头的寿命与各种尺寸和形状。实验验证测试证实了计算的有效性和良好的协议之间的理论预测和实验数据。
In the present paper, a crack propagation-based fatigue life estimation approach has been proposed for resistance spot welds. The presented approach also takes into account the effect of welding residual stresses. It can provide an accurate and systematic prediction of the life of spot weld joints with various dimensions and shapes. Experimental verification tests confirmed the validity of the calculations and good agreement was found between the theoretical predictions and experimental data.
