[33] Optimization of the Parameter in Huddleston Stress for Creep Rupture Time Evaluation of 2 1/4Cr-1Mo Weld Joints

*Hitoshi IZUNO1, Masahiko DEMURA1, Masayoshi YAMAZAKI1, Masaaki TABUCHI2, Daisuke ABE3, Keisuke TORIGATA3 (1. NIMS MaDIS, 2. NIMS RCSM, 3. IHI)

Keywords:Weld Joint、Time Exhaustion Rule、Huddleston Stress、Two Quarter Steel、Rupture Time Prediction、Finite Element Method、Parameter Optimization

2 1/4Cr-1Mo鋼継手試験片の時間消費測を用いたFEM解析によりクリープ破断寿命計算を行い,実試験と計算の破断寿命誤差和をコスト関数としたHuddleston応力のパラメタbの最適化により実験再現性を改善した.
