Abstract
This study deals with the stress analysis and the strength evaluation of an adhesive butt joint combining a coupling collar when the joint is subjected to an internal pressure and a temperature change. The stress distributions at the interface between the adherends and the adhesive in the joint are analyzed by using the axisymmetric finite element method (FEM). In addition, the rupture test of the joint was carried out by applying an internal pressure and a temperature change to the joint. From the numerical calculation and the experiment, strength of adhesive butt joint combining a coupling collar is estimated by using the stress distribution at the interface obtained from the FEM analysis.
