Abstract
In this study, joint strength and failure characteristics were experimentally examined with pull-out and shear specimens in which new designed "high strength insert" was applied. The performance of the new insert was compared with typical insert design. The experimental results showed that the "high strength insert" had the joint strengths of 2.1 times in the pull-out specimens and 2.04 times in the shear specimen compared with typical insert joints. Therefore, the new developed "high strength insert" will be usefully used in the aerospace structure.
