Optimization problems for a thermoelastic frictional contact problem
Mathematical Modelling and Analysis, 2021 In the present paper, we analyze and study the control of a static thermoelastic contact problem. We consider a model which describes a frictional contact problem between a thermoelastic body and a deformable heat conductor obstacle.

Mathematics in Finite Element Modeling of Computational Friction Contact Mechanics 2021–2022
Mathematics, 2023 In engineering practice, structures with identical components or parts are useful from several points of view: less information is needed to describe the system; designs can be conceptualized quicker and easier; components are made faster than during ...

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

Cylindrical shells and panels subject to bilateral and unilateral contact constraints [PDF]
REM: International Engineering JournalThe cylindrical shell-medium (soil or rock) contact problem solution is typically achieved through numerical methods, where the modeling or approximation of the medium’s behavior is usually made considering it as an elastic deformable foundation that ...
