Torque transmission capability of composite-metal interference fit joints

Abstract

In this paper the performance of an interference fit joint between a composite tube and a steel shaft under torsional load was investigated. Some important design parameters on the interference fit joint were presented and addressed based on the results from analytical and numerical models. The stress state of the joint under torsional load with contact elements was calculated by three dimensional finite element analysis. For the long term use of the interference joint the viscoelastic behavior of the composite tube was also considered through the analytical model. Finally the validity of analysis of the interference fit joint was experimentally examined. (c) 2005 Elsevier Ltd. All rights reserved.
