I보 단면을 보 / 쉘 요소로 모델링 후 수치적으로 모드들을 도출하는 기존 연구들과 달리, 제안하는 재귀 분석법은 해석적으로 모드들을 유도한다. 따라서 유도된 모드의 형상함수들이 I보 단면 치수에 무관하게 적용 가능한 닫힌 형태(closed-form)로 기술되는 특징을 지닌다. 또한 재귀 분석법을 통해 유도되는 형상함수간의 재귀적 관계는 기존에 구축되지 못했던 I보에 관한 고차 보 이론의 명시적 응력-힘 관계를 제공한다. 제안하는 재귀 분석법의 유효성은 I보의 변위 / 응력 분포들을 해석하는 다양한 예제들을 통해 검증하였다.","PeriodicalId":23293,"journal":{"name":"Transactions of The Korean Society of Mechanical Engineers A","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136272398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
