Strain-based critical plane approach to predict the fatigue life of high frequency mechanical impact (HFMI)-treated welded joints depending on the material condition

After post-treatment with high frequency impact treatment (HFMI) of weld toes, a significant increase of fatigue strength or fatigue life can be achieved. Due to the lack of methods for the quantitative prediction of the HFMI benefits depending on the process and treated material, a widespread use of this process has not yet happened. One reason for that issue is that at the moment, no methods exist to predict the influence of the HFMI-treatment...
