In the present study, to develop an evaluation procedure and design rules for Mod.9Cr-1Mo steel weld joints, a method for creep-fatigue life evaluation of Mod.9Cr-1Mo steel weld joints was proposed based on the finite element analysis (FEA) results with a series of cyclic plate bending tests of the longitudinal and horizontal seamed plates. The strain concentration and redistribution behaviors were evaluated and failure cycles were estimated using FEA by considering the test conditions and metallurgical discontinuities in the weld joints. The elastic follow-up factors calculated from a comparison of the elastic and inelastic FEA results were determined to be less than 1.5. Based on the estimated elastic follow-up factors obtained via inelastic FEA, a simplified technique using elastic FEA was proposed for evaluating the creep-fatigue life in Mod.9Cr-1Mo steel weld joints.
