本研究では、改良9Cr-1Mo鋼製の多孔板試験体の疲労及びクリープ疲労試験の行い、その結果を用いて種々の構造物の疲労およびクリープ疲労寿命の評価方法を比較・検証を行った。具体的には、多孔板試験体の試験では550$$^{circ}$$Cにおいて機械的繰り返し荷重を加え、孔の表面における亀裂の発生と伝播を観察するとともに、一連の有限要素解析に基づいて、種々の破損寿命評価方法により破損繰返し数を予測して、試験結果と予測結果の比較検証を行た。

This study compares and assesses the different fatigue and creep-fatigue life evaluation methods by performing tests of perforated plate made of Mod.9Cr-1Mo steel. Multi-perforated plate was subjected to mechanical cyclic loading at 550$$^{circ}$$C, and crack initiation and propagation on the surfaces of the holes were observed. A series of finite element analyses were carried out to predict the number of cycles to failure by the several failure life evaluation methods, and these predictions were then compared with the test results. Several types of evaluation methods that use the elastic FEA were applied.
