Description / Table of Contents:
Influence on the fatigue behavior of notched specimens by different wear and tear of the tools used for producing the notches. In fatigue-specimens of × 5 CrNi 18 9 and Ck 45 notches had been produced by sharp and blunt tools. The fatigue strength of this specimens from austenitic steeel was smaller when the notches had been produced by sharp and blunt tools. The fatigue strength of this specimens from austenitic steeel was smaller when the notches had been produced by sharp tools. Specimens of ferritic steel on the contrary had a greater fatigue strength, when the notches had been produced by blunt tools. Statistical methods had been used for planning and evaluation of the tests. Therefore appear differences in the strength reduction factor ßk between in conventional manner determined statements and the here calculated ones.
Notes:
An Dauerschwingproben aus X 5 CrNi 18 9 und Cl 45 wurden Kerben mit scharfen und stumpfen Werkzeugen hergestellt. Die Dauerschwingfestigkeit der Proben war bei mit stumpfem Werkzeug hergestelltem Kerb beim austenitischen Stahl kleiner, beim ferritischen größer als bei mit scharfem Werkzeug hergestelltem Kerb.Alle Versuche wurden nach statistischen Verfahren angesetzt-und ausgewertet. Dadurch ergeben sich bei Vergleichen des Kerbwirkungsfaktors ßk mit auf konventionellem Wege ermittelten Werten von ßk Abweichungen.
