Using the finite‐element program MARC developed by MARC Analysis Corporation, thermal stresses are calculated for a simple sandwich seal and a bead seal under conditions of uniform cooling, reheating, and an isothermal hold and for a tempered glass plate. Results of the viscoelastic calculations are compared with previously obtained analytical solutions and with experimental stress measurements. The formalism for including viscoelastic material properties in the program is developed.
