Structural Stress–Fatigue Life Curve Improvement of Spot Welding Based on Quasi-Newton Method

Structural Stress–Fatigue Life Curve Improvement of Spot Welding Based on Quasi-Newton Method

Abstract ∆F-N curves are usually used to predict the fatigue life of spot welding in engineering, but they are time-consuming and laborious and not universal. For the purpose of predicting the fatigue life of spot welding accurately and efficiently, tensile–shear fatigue tests were conducted to obta...
