Description
  • The topic of the present paper is the analysis of the histogram stress range uncertainty influence on the fatigue resistance uncertainty. The maximum number of cycles of an element with crack initiation. up to reaching the brittle fracture is considered to be fatigue resistance. Reliable results can be obtained, when the stress range histogram is exactly known from very good experimental results for the whole structure service life. In the opposite case, the histogram is a source of vague (fuzzy) uncertainty. In the stochastic approach, the difference of histogram sis substituted by standard deviation of equivalent stress range. The fuzzy analysis offers an innovative approach; in the frames of this type of analysis, the input histograms are considered to be members of a fuzzy. The fuzzy random analysis of fatigue resistance is presented in the paper conclusion.

  • Předmětem článku je analýza vlivu neurčitosti histogramu napětí na neurčitost únavové odolnosti. Za únavovou odolnost je považován maximální počet cyklů prvku s iniciační trhlinou až do dosažení křehkého lomu. Spolehlivé výsledky lze získat pokud je histogram napětí exaktně znám z kvalitních experimentálních výsledků za celou dobu životnosti konstrukce. V opačném případě je histogram zdrojem vágní (fuzzy) neurčitosti. Ve stochastickém přístupu je odlišnost histogramů substituována směrodatnou odchylkou ekvivalentního napětí. Inovační přístup nabízí fuzzy analýza, ve které jsou vstupní histogramy uvažovány jako prvky fuzzy množiny. V závěru článku je prezentována fuzzy náhodná analýza únavové odolnosti. (cs)
