Abstract

This paper presents a two dimensional p-version static infinite element for analyzing $1/r^n$ displacement decay type problems in unbounded media. The proposed element is developed by using shape functions based on approximate expressions of an analytical solution. Numerical results are presented for an opening in a homogeneous elastic infinite medium and a rigid footing rested on a homogeneous elastic half-space. The numerical results show the effectiveness of the proposed infinite element.

본 논문에서는 무한영역에서 발생하는 임의의 1$1/r^n$변위감쇠특성을 해석할 수 있는 p-버전 정적 무한요소를 연구하였다. 무한요소를 개발하기 위하여 이론해를 근사화한 형상함수를 사용하였다. 균질한 무한 탄성체내의 공동변형문제와 반무한탄성체위에 놓인 강성기초의 거동해석을 통하여, 본 연구에서 개발된 무한요소가 무한영역을 효율적으로 묘사할 수 있음을 검토하였다.
