Abstract

The effects of the ovalization of the tangential pipes to the elbows are analyzed. The geometric nonlinear behaviors of the elbows are shown with the element capable of ovalization. The relationships between the length of the tangential pipes in the models and the bend angles of the elbows are analyzed to supplement the ASME code. And the proper length of the tangential pipes for the elbow models are suggested.

단면의 타원변형을 고려할 수 있는 요소를 사용하여 엘보우의 기하학적 비선형 거동을 설명하고 직선배관의 타원변형이 엘보우에 미치는 영향을 파악하였다. 또한 직선배관의 길이와 엘보우 휨 각도 사이의 관계를 파악하여 ASME 코드 식의 보완점과 올바른 해석결과를 얻는데 필요한 직선배관의 길이를 제시하였다.
