RT Journal Article SR Electronic A1 Kaľavský, Adam A1 Huňady, Róbert A1 Lengvarsky, Pavol T1 Spectral fatigue life for simple notched component JF Manufacturing Technology Journal YR 2020 VO 20 IS 5 SP 612 OP 616 UL https://journalmt.com/artkey/mft-202005-0005.php AB The paper describes a procedure for calculating the lifetime in the frequency domain, which is supplemented by an experiment. The aim of the experiment was to find the required mechanical properties of the material to describe the behavior of the material during fatigue analysis. Experimental modal analysis was performed to estimate damping, which supported numerical calculation and refined results of numerical simulations. The authors made an estimate of fatigue curve (SN-curves) according to ČSN 42 0363 and ČSN ISO 12 107 standards. Knowledge of material fatigue, statistics, modal analysis and signal processing were used in the experimental and numerical part.
