  • The impact of the structural non-linearity on the vibration fatigue damage accumulation [Elektronski vir]
    Proso, Uroš ; Slavič, Janko, 1978- ; Boltežar, Miha
    High cycle vibration fatigue is the main cause for the damage in structural components which accumulates while structure is excited by random dynamic loads. Significant influence of the structural ... non-linearity on the damage accumulation is supposed. A validated numeric investigation of a linear dynamic structure is used for vibration fatigue damageaccumulation estimation. The accelerated vibration tests are performed for vibration fatigue lifetime determination and non-linearity quantification. The structure is excited at increasing excitation levels where an increasing level of non-linearity is observed by a FRF based approach. The FRF based structural non-linearity rate is used for the linear damage accumulation correction. The research is expected to give results with applicability to similar cases and opens up new potential in the field of structural - vibration fatigue optimization.
