Header design ideology and material selection are described. Current header designs utilize a glass-ceramic insulator which is bonded to a current carrying pin and a metal shell. Residual stresses in the header occur as a result of cooling from the glass softening temperature and are attributable to differences within the header material set in coefficients of thermal expansion. A stress analysis is undertaken to model the residual thermal stresses in glass-ceramic headers. A feature of this model is that it simulates bonding at glass-ceramic to metal interfaces by precluding interfacial sliding. Residual stresses for four material sets are analyzed. These material sets are chosen to illustrate the various stress states which can arise due to differing combinations of coefficients of thermal expansion within a material set. 9 refs., 10 figs., 2 tabs.
