摘 要: The influence of notches and load conditions on the fatigue limit of the high-strength steel SAE 52100 is investigated. The behaviour can be described quantitatively by a weakest-link concept which describes competitive crack initiation at the surface and at inclusions. This includes the possibility of calculating local and total endurance probabilities depending on the nominal stress amplitude. Crack initiation sites and the fatigue limit can also be predicted. The basic relation between the size distribution of crack-initiating inclusions and the fracture probability was proved for smooth specimens under tension-compression.

研究了缺口和载荷条件对高强度钢SAE 52100疲劳极限的影响。该行为可通过“最薄弱环节”概念进行定量描述,该概念揭示了在表面和夹杂物处的竞争性裂纹萌生。基于名义应力幅值,可计算局部及总耐久概率。同时,还可预测裂纹萌生位置和疲劳极限。在拉压试验中,已证明了裂纹萌生夹杂物的尺寸分布与断裂概率之间的基本关系。
