Three-Dimensional Analysis of Composite External Fuel Tank Joint
항공기용 복합재 외부연료탱크 체결부의 3차원 구조해석
Abstract
A composite-aluminum hybrid joint of composite external fuel tank of an aircraft has been analyzed by a 3-dimensional finite element method. Curvature and contact of the joint structure were considered in the analysis. Yamada-Sun failure criteria was utilized for the failure evaluation. A finite element program ABAQUS was used for the nonlinear contact analysis. The joint structure was predicted to be safe in both the test and analysis.
