Analysis of the stress disribution around flaws and the interaction effects between fatigue cracks by finite element method
유한요소법에 의한 결함 주위의 응력분포와 피로크랙의 간섭효과
Abstract
In order to analysis of the stress distribution around flaws and the interaction effects between fatigue cracks, stress around micro hole was analyzed by Finite Element Method(F.E.M.) and micro hole specimens were tested using rotary bending fatigue machine and twisting fatigue machine to identify stress effects for fatigue cracks initiating from micro holes and interaction effects between micro holes. The results are as follows : Interaction effects of .sigma.
