Abstract
Transient thermal stress distribution in an adhesive butt joint is dealt with in this study. It is assumed that both the upper and lower end surfaces of the joint are subjected to different temperatures at a certain instant in time and the side surfaces of the joint are kept at a constant temperature. In the analysis, two adherends and an adhesive layer are replaced with finite strips and unsteady, two-dimensional temperature distribution in the joint is obtained theoretically. Then, the transient thermal stress distribution in the joint is analyzed using a two-dimensional theory of elasticity. The effects of the adherend to adhesive ratios of the Young’s moduli and thermal expansion coefficients on the transient thermal stress distribution are clarified using numerical calculations.
