Abstract
The effects of the fillet, which was formed by melted brazing at the brazing temperature, on the residual stress in the Al_2O_3/Cu joints were studied by the finite element analyses. The stress distributions near the joining interface show that the brazing fillet can diminish the stress singularity at the edge of the joining interface. So an optimum design of the joint structure can significantly improve the strength of the ceramic/metal joint.
