摘要: Abstract The creep properties of the P92 steel were evaluated by small punch (SPC) tests and uniaxial (UC) tests. In addition, finite element (FE) methods using different damage models adopted to analyze variation deformation process for SPC tests, validity FE was confirmed comparison experimental accumulation. rupture time, fracture positions crack growth behaviors dependent on model. friction coefficient also discussed effect properties. On basis these results, average equivalent stress at center specimen proposed correlate load in UC Then, relationship data results established. Larson–Miller master curves obtained from indicated that strain-based model an appropriate evaluate long term life. more suitable steel.
