Calculation of interfacial stress in porcelain-fused-to-metal systems
R. L. Bertolotti
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.
