摘要：

This paper presents experimental results on fatigue and creep-fatigue experiments consisting of a wide cracked plate subjected to cyclic bending loads at 650degreesC. Six tests have been realised with different loading histories. The specimen is a large 316SS plate containing a wide semielliptical surface notch precracked by fatigue. Fatigue and creep crack growth laws are determined, using an adapted stress intensity factors compendium calculated by F.E. elastic analysis, and compared to tests results conducted on CT specimen. A good correlation of the experimental results for fatigue tests is obtained. For creep crack growth law, the CT specimen gives an intermediate result between plate results at the deepest point and at the surface point. A16 guideline assessment procedures are used; results are found to be in good agreement with experimental crack growth. (C) 2002 Elsevier Science Ltd. All rights reserved.
