Design optimization of metal-to-ceramic joints
The design optimization of metal-to-ceramic joints was discussed. The five design variables discussed were diameter of the molybdenum rod, outer diameter of the alumina tube, overhang of the alumina tube and cermet on the outside of the joint, length of the cermet, and weight fraction of the tungsten in the cermet. It was noticed that cermet underwent tensile strains at interface with molybdenum and compression strains at interface with alumina. This strain mismatch in thermal expansion coefficients caused joint failure.
