Abstract

The theoretical analyses of the stress distribution in bonded joints are of little help to the practical designer. An approximate solution yields an expression for the “average” ultimate shear stress in terms of two constants. This paper shows how these constants can easily be determined experimentally and gives test results which show their temperature dependence and their variation under fatigue-loading conditions. The constants are essential characteristics of a given adhesive and can be used to design any glued joint using this adhesive.
