INTEGRATION OF DAMAGE DIFFERENTIALS (IDD)
FOR FATIGUE LIFE ASSESSMENT UNDER ANY LOADING
Last updated: September 9, 2025
NEWS AND DISCUSSION
With regard to Chapter 6 of my DSc thesis, I reported at the INNO-2012 Conference and published:
Stefanov S. H. Development of a Model for the Variable Tensile Stress in Band-Saw Blade. Innovations in Forest Industry and Engineering Design, 2/2013, Vol. II, 113 - 122
This is a statically indeterminate problem posed and solved for the tensile stress in the sections of a band-saw blade – something that has not been done in the research on band saws.
