一种复合材料-钢连接结构极限承载能力试验与数值研究
The Experimental and Numerical Research on the Extreme Bearing Capacity of a Composite- Steel Connecting Structure
摘要
Abstract
The composite sandwich plate has been widely used in the ship industry due to its excellent me⁃chanical property and antiseptic property. In this paper, a sandwich composite component applied on a com⁃posite deck-house(composite-steel connecting structure)is studied,whose design load and ultimate load requirements are obtained by analyzing the stress and strain of laminates under specific loads. Also,the classical lamination theory, Reissener sandwich plate theory, Hoff sandwich plate theory,and Du Qinghua sandwich plate theory are compared, where Hoff sandwich plate theory is finally chosen as the proper theo⁃retical model to verify the reliability of the presented technique. With finite element software simulation analysis, the actual results obtained in the test are validated through numerical simulation, which provides meaningful guidance for the future design of sandwich composite connecting structures.关键词
