heal.abstract	The current post-graduate thesis studies thermomechanical problems. Thermomechanics is the field of Mechanics that studies temperature field problems and the effects of temperature variation on the mechanical behavior of a body. The specific thesis will be limited in the area of Generalized Linear Thermoelasticity. Initially, the fundamental theory of Linear Thermoelasticity is presented. Detailed attention is given to the basic principles of Continuum Mechanics, the First and Second Laws of Thermodynamics and Fourier’s Law of heat conduction. Consequently, the classical model (based on Fourier’s Law) and the non-classical models (Lord-Shulman, Green-Lindsay, Green-Naghdi) of Thermoelasticity are given.The classical and non-classical models constitute the extended model of Generalized Thermoelasticity. Numerical methods are used for the solution of the thermoelastic problems. The Finite Difference Method and the Finite Element Method are presented. Using the fundamental theory and the two numerical methods mentioned above, five types of thermomechanical problems are studied. The thermomechanical problems are the following: (1) Study of the elliptic, parabolic and hyperbolic type of heat conduction, (2)Thermal stress analysis of a plate, (3) Thermal stress analysis of a thicked cylinder, (4) Thermoelastic analysis of a 2d component that consists of 2 different materials, (5) Study of the thermomechanical behavior of an elastic hollow sphere. Finally, the results of the applications are discussed and suggestions for future research are presented. For the synthesis of the thesis, the following software was used: Microsoft Office, Mathtype, Matlab and ANSYS Mechanical APDL.	en
