Abstract

Abstract

Formative position of fatigue crack, and fatigue life of asymmetric notched component are investigated.A stress field intensity function, which reflects effect of the equivalent stress at perilous point and that of the stresses and its gradient within the damage area on crack formation, is presented.
- stress field intensity method,
- asymmetric notch,
- crack formation,
- equivalent stress,
- stress gradient
