| Abstract: | Two kinds of variational principles for numerical simulation of heat transfer and contact analysis are respectively presented.
A finite element model for numerical simulation of the thermal contact problems is developed with a pressure dependent heat
transfer constitutive model across the contact surface. The numerical algorithm for the finite element analysis of the thermomechanical
contact problems is thus developed. Numerical examples are computed and the results demonstrate the validity of the model
and algorithm developed.
