Abstract

The boundary element analysis has been attempted for investigating the singular stress at the interface edge of infinitely layered structure. The subdomain technique has been employed and the analysis model has been divided into two subdomains, which are respectively homogeneous elastic zones. The boundary element equation has been formulated using the equilibrium and continuity conditions at the common interface. The numerical results of example problem has been presented.

이 논문에서는 경계요소법을 사용하여 서로 다른 탄성체들이 무한하게 적층된 복합구조체의 자유경계면에서 발생하는 특이 응력을 조사하였다. 종속영역법을 도입하여, 해석모델을 독립된 탄성영역들로 나누었고, 해석모델의 공유경계면에 변위연속조건과 표면력 평형조건을 적용하여 경계요소공식을 유도하였다. 예제의 문제에 대한 수치해석 결과를 제시하였다.
