A Study on the Strength of Mechanically Fastened Composite Joint Using the Linear Analysis

선형해석을 이용한 복합재료 기계적 체결부의 강도평가에 관한 연구

With the wide application of fiber-reinforced composite material in aero-structures and mechanical parts, the design of composite joint have become a very important research area because they are often the weakest areas in composite structures. In this paper, the failure area index method to predict the failure load of the mechanically fastened composite joint was used and the prediction accuracies of the linear finite element analysis were compared with those of nonlinear finite element analysis.
