Temperature Effects on the Strainrange Partitioning Approach for Creep Fatigue Analysis

Source

Examination is made of the influence of temperature on the strain-range partitioning approach to creep fatigue. Results for 2¼Cr-1Mo steel and Type 316 stainless steel show the four partitioned strainrange-life relationships to be temperature insensitive to within a factor of two on cyclic life. Monotonic creep and tensile ductilities were also found to be temperature insensitive to within a factor of two.

The approach provides bounds of cyclic life that can be readily established for any type of inelastic strain cycle. Continuous strain cycling results obtained over a broad range of high temperatures and frequencies are in excellent agreement with bounds provided by the approach.
