1.
An Investigation on the Relation between the Fatigue Crack Propagation Threshold and Grain Size The Application of the Dislocation Theory;
疲劳裂纹扩展门槛值与晶粒尺寸关系的研究—位错理论的应用
2.
In contrast with the threshold of fatigue cracks,a series of regulation of expanding of fatigue small cracks has been deduced.
采用对比分析方法,从疲劳裂纹的门槛值角度出发,归纳总结了疲劳裂纹的扩展规律。
3.
Near-threshold fatigue crack propagation tests were conducted under combined torsion and tension on a circumferentially pre-cracked round bar of an austenite stainless steel.
研究了带环状预裂纹的奥氏体不锈钢圆棒试样在循环扭转／拉伸复合载荷下,门槛值附近的疲劳裂纹扩展行为,分析了复合加载时不同载荷比对裂纹扩展的影响,对裂纹扩展的初始阶段进行了详细研究,用应力强度因子表征了裂纹扩展开始的门槛值,提出了椭圆方程表达的疲劳裂纹扩展开始的门槛值模型,该方程可在裂纹尖端位移准则的基础上导出,疲劳裂纹扩展停止的门槛值条件也可用椭圆方程表达。
