“疲劳裂纹扩展位错模型”的概念、定义、翻译、参考文献-科学参考

单词	疲劳裂纹扩展位错模型
释义	疲劳裂纹扩展位错模型 Encyclopedia 工学疲劳裂纹扩展力学模型释 dislocation model of fatigue crack growth疲劳裂纹扩展位错模型在外加载荷作用下，裂纹尖端附近的材料会发生屈服，说明裂纹前端塑性区有位错的产生和运动。由应力集中形成的某些力会把位错移出塑性区，而与材料弹性极限相关的摩擦力则阻止位错的这种移出行为。基于这种力的平衡关系，导出裂纹尖端在每个循环中的位移量，当位移总和达到某个临界值时，裂纹便向前扩展并释放出循环过程中的能量，得到相应的裂纹扩展速率与外界功的函数表达式。
