Abstract:
Based on the study results of the fatigue life distribution, the
fatigue strength distribution characteristics of a HSLA steel was
studied in this paper, and the fatigue strength distribution has been
derived from the conversion relationship between the fatigue life
distribution and the fatigue strength distribution. Research results
show that the fatigue strength distribution is not normal but skew. For
the above distributions, the P-S-N space curved surface which expresses
the fatigue failure probabitity was drawn, and the curved surface will
play an important role not only in practice but also in theory.
