Analysis of a Crack Emanating from a Circular Hole of a Finite Sheet under Uniform Stress Boundary Condition
Abstract
균열이 있는 원공을 가진 유한평판이 균일응력을 받을 때 균열길이가 응력확대계수와 응력, 변위에 미치는 영향을 연구하였다. ?邕源疫萱? Bowie에 의해 소개된 Modified Mapping Collocation Method를 사용하였다. 평판의 높이와 폭의 비는 1로 고정하였고 균열길이와 폭의 비는 0.3부터 0.7까지 변화시켰다. 그 결과 균열길이가 증가함에 따라 응력확대수정계수가 증가하였으며 응력과 변위도 큰 변화를 보였다. 또 원공의 반경이 증가할수록, 평판 높이와 폭의 비가 감소할수록 응력확대수정계수가 증가함을 알 수 있었다.
The effect of a crack length on the stress intensity factor, stress and displacement distributions has been studied for a finite sheet having a cracked circular hole under a uniform stress boundary condition.

The computation was accomplished using MMC(Modified Mapping Collocation) method introduced by Bowie. Height-to-width ratio was fixed to 1 and crack length-to-width ratio varied from 0.3 to 0.7. As crack length increased, stress intensity factor increased and the stress and displacement distribution varied remarkably.

As the radius of the hole increased and height-to-width ratio decreased, stress intensity factor increased.
