Multidimensional Contact Problems in Thermoelasticity [PDF]

SIAM Journal on Applied Mathematics, 1998
Summary: We consider dynamic and quasi-static thermoelastic contact problems in \({\mathbb R}^n\) modeling the evolution of temperature and displacement in an elastic body that may come into contact with a rigid foundation. The existence of solutions to these dynamic and quasi-static nonlinear problems and the exponential stability of the solutions are
