Calculation of interfacial stress in porcelain-fused-to-metal systems.
A method is given for calculating interfacial shear stress in porcelain-fused-to-metal restorative materials. Thermal history of the porcelain and dynamic stress relief relations are utilized to predict interfacial stress as a function of temperature. Calculations are in agreement with experimental results based on the deflection of bimaterial strips and are consistent with previously reported data.
