Abstract

In this paper, the static and dynamic behavior of partly wrinkled membrane was studied. Membrane finite elements were used in the analysis and the wrinkling in the element was accounted for by a penalty-parameter material modeling which was implemented as a user subroutine to ABAQUS. The wrinkle algorithm was applied to a corner-loaded square membrane to investigate the effect of wrinkling on the static and dynamic behavior.

본 논문에서는 멤브레인 요소를 사용하여 주름이 있는 멤브레인의 정적 및 동적거동을 연구하였다. 해석은 상용유한요소 프로그램인 ABAQUS를 사용하였으며 멤브레인 요소에서 주름은 벌칙매개변수에 의한 물성치 수정 방법을 사용자 부프로그램으로 구현하여 고려하였다. 해석과정은 먼저 이론해가 멤브레인 문제에 적용하여 타당성을 검증하였고, 모서리에서 하중이 가해진 사각형 멤브레인에 대한 해석을 수행하여 주름이 정적 및 동적거동에 미치는 영향을 조사하였다.
