초록
본 논문에서는 굽힘과 내압이 가해질 때 미터밴드의 한계하중을 3차원 유한요소해석을 이용하여 연구하였다. 재료는 탄성-완전 소성재료로 가정하였고, 기하학적 선형과 비선형 효과를 고려하여 소성 한계하중을 결정하였다. 본 연구를 위한 해석에서는 다양한 범위의 형상 변수가 고려되었다. 유한요소해석 결과를 바탕으로 굽힘에 관한 보간식을 제시하였다.
Abstract
Based on three-dimensional(3-D) finite element limit analyses, this paper provides limit and TES (Twice-Plastic Load) loads for mitred pipe bends under bending and pressure. The plastic limit loads are determined from FE limit analyses based on elastic-perfectly-plastic materials using the small and large geometry change option. A wide range of parameters related to the mitred bend geometry is considered. Based on the finite element results, closed-form approximations of plastic limit and TES plastic load solutions for mitred pipe bends under bending are proposed.
