Two alumina cylinders of commercial purity, 10mm high and 10mm in diameter were bonded together using an aluminum film. In addition to the normal bonding process, bonding under alternating bonding pressure was performed, and the effect of the alternating applied stress on the bonding strength of the joint was investigated based upon the statistical analysis. A fairly good agreement is obtained between the calculated and the observed strength distributions of the joint. The present analysis has led to the conclusion that alternating stress imposed during the bonding process is effective to reduce the formation of macro bonding flaws, resulting in higher bonding strengths.
