Creep-Fatigue Life Prediction for Different Heats of Type 304Stainless Steel by Linear-Damage Rule,Strain-Range Partitioning Method,and Damage-Rate Approach.

摘要

The creep-fatigue life results for five different heats of Type 304stainless steel at 593exp 0 C (1100exp 0 F),generated under push-pull conditions in the axial strain-control mode,are presented. The life predictions for the various heats based on the linear-damage rule,strain-range partitioning method,and damage-rate approach are discussed. The appropriate material properties required for computation of fatigue life are also included. (ERA citation 04:013973)
