Adding Additional Load Paths in a Bonded/Bolted Hybrid Joint

摘要

Hybrid (bonded/bolted) joints are usually used in lap joints in order to achieve the fail-safe capability. However,nthe mechanical bolt is inactive until the adhesive bond fails, making the hybrid joint weightwise inefficient. In thenpresent work, a newdesign of a hybrid joint with attachmentswas conceived and investigated. This design used thin-nplate attachments to provide an additional load transfer path to activate the load-bearing capability of the bolt.nExperimental investigations were conducted on the conventional joint designs and the new joint design. The jointnstrength of the new design was found to be 80% higher than the conventional hybrid joint. In addition to thendevelopment and testing of the new joint design, finite element analysis was performed to study the load distributionnin different parts of the joint and to compare stress distributions in different joint configurations.
