DETERMINING OF FATIGUE LIMIT OF PART SUBJECTED MULTIAXIAL STRESSES BY NUMERICAL METHOD ABSTRACT This paper presents the results of calculating the fatigue limit of the part subjected multiaxial stresses by numerical method. The multiaxial stress field of the part is equivalently converted to the stress field used in the calculation on the basis of different criteria, these evaluation criteria have been commonly used to determine the fatigue properties of part subjected multiaxial stresses. Calculation results are compared with published test results and international standard, through comparison, it is shown which evaluation criteria are most suitable for fatigue limit assessment for complex stressing part. Keywords: Fatigue limit, multiaxial stress, multiaxial fatigue |
