Fatigue life estimation of spot welded joints using an interpolation/extrapolation technique

A numerical interpolation/extrapolation technique is presented that can utilize the fatigue life and strength databases of spot welded joints that have been developed by previous researchers. These databases typically included multiple independent variables, such as specimen dimension and type, material property, R-ratio, and welding condition, such as are often encountered in a typical design of experiments approach to testing. In this study,...
