Designing of mechanically fastened joints in composite structures
- Kyoto Inst. of Tech., Matsugasaki, Kyoto (Japan). Faculty of Fiber Science
In this study, mechanical behavior and designing method for multiple-joints were examined. Three joint forms, which were single-hole joints, two-holes in parallel and two-holes in series, were chosen. As a result, the behavior of the multiple-joints was different with that of single-holed joints. Especially, joints that exhibited bearing failure in single-hole joints appeared net-tension failure in two-holes in series. So it is cleared that designing using the data of single-hole is very dangerous since bearing failure appears safety fracture propagation and high strength but net-tension failure appears risky fracture propagation and low strength. So it is necessary to examine the design method that considers the stress distribution of multiple-joints. The proposed strength prediction method using a numerical analysis was applied to multiple-joints. It is cleared that the real jointed structures can be designed by the proposed method since good agreement was obtained between experimental and predicted joint strength.
