Stress Effects on Activity of Primary Cracks Initiating at Stress Concentrator
응력 집중원에서 발생하는 초기 균열의 거동에 미치는 응력장의 영향
Abstract
This study has been performed to investigate the stress distribution around defects that behave as stress concentrators and fracture mechanical analysis for cracks initiatiating at stress concentrators. The stress distribution was analyzed using Finite Element Method and non dimensional stress intensity factor was determined by the mean stress method. In addition, stress interaction effects around defects and cracks were compared.
