Filed: 2003-04-28
Abstract: <P>PROBLEM TO BE SOLVED: To accurately predict the life of engine parts until resulting in breakage by three breaking factors of low cycle fatigue, creep and high cycle fatigue without constructing a large-scale database requiring immense man-hours.  <P>SOLUTION: The life of engine parts when each breaking factor is independently applied is obtained by an experiment and set to databases DB11-13.

The amount of creep fatigue damage is computed considering the influence of stress relaxation by interaction. The amount of high cycle fatigue damage is computed considering the influence of damage caused by vibration of a fatigue limit or less. Breaking is determined when the total of the damage amounts by three breaking factors becomes a prescribed value.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
