金屬材料的閾限應力強度因子和疲勞裂紋增長率的測定方法There is a slight drop of the fcpr when the specimen s thickness increases. however, the thickness of the specimen exerts a great influence on kth and fatigue life ( n ) : the thicker specimen is, the higher fatigue life ( n ) becomes, and the greater kth shows. under control of the same conditions, the fcpr of am50 is not so high as that of az91. there are some correlations between load ratio ( r ) and the fatigue surface : when load ratio becomes great, small flat surfaces increase while dimples decrease
試樣厚度增大，穩態裂紋擴展速率略有減小。但是，試樣厚度影響試樣的疲勞壽命和門檻值：試樣越厚，疲勞壽命越長，門檻值越大；在試樣尺寸和加載條件相同的情況下， am50的疲勞裂紋擴展速率較az91小，疲勞壽命則比az91長。載荷比r影響試樣的斷口形貌：載荷比r越大，對應相同k值出的斷口小平面越多，韌窩越少。Polyethylene pipes - resistance to slow crack growth - cone test method
