5Mo steel under stress control of trapezium waveforms at 540℃,life prediction for fatigue-creep interaction of 1.

5Mo steel under stress control of trapezium waveforms at 520℃ and 540℃,the rule about fatigue-creep interaction of notched specimens at elevated temperature were studied.

Results showed that the curves of fatigue/creep had three stages when the maximum of alternating load was 75% failure load of wood-bamboo composite board.

Results showed that the curves of fatigue/creep have three stages at the 75% stress and the curves of fatigue/creep have two stages at the 55% stress.

Discussion of life prediction for fatigue-creep interaction;

Investigation on probabilistic model for fatigue-creep failure of alloy GH30;

The fastening bolts of steam turbine cylinder case were in fatigue-creep interaction.

The resultsshow that the interaction of creep fatigue is the primal failure mode for the coking column and the most dangerous place islocated at the welded zone of its lower part.

The failure mode could be classified as the creep fatigue and the complex high cycle and low cycle fatigue fracture resulted from initially high stress.

Some special subjects of the fatigue life prediction on aircraft structures encountered in recent years,such as fatigue under the alternative of corrosion or cyclic loading,creep fatigue of polymethyl methacrylate,fatigue under stochastic vibration loading and cyclic loading,fatigue of fibre reinforced polymers,are reviewed.

A new experimental method,in which the turbine blade was loaded by applying friction force and heated by eddy current induction,was proposed to study creep/fatigue life of directionally solidified alloy turbine blade.
