K. Kobayashi et al., LOW-CYCLE FATIGUE LIFE ANALYZED BY PARAME TER METHOD FOR VARIOUS HIGH-TEMPERATURE MATERIALS, Tetsu to hagane, 79(11), 1993, pp. 1288-1292
Low-cycle fatigue life for various kinds of high temperature materials
has been analyzed by a modified Larson-Miller parameter. written by P
= T (logN25 - Alog epsilon + B), where T is temperature, N25 is fatig
ue life under symmetrical strain wave shapes. Epsilon is strain rate,
and A and B are constants. Test data used in the analysis are from NRI
M Fatigue Data Sheets of popular engineering materials of nine kinds.
ten heats including carbonsteel to Fe-base super alloy. The results ha
ve been compared between the materials and compared with statistical a
nalysis results adopted in a design code.
