The book deals with concept of thermoelasticity, which is gaining popularity as a field of research, and finds vast applications in space science and engineering field, specially the heavy engineering field. Thermoelastic behavior of different isotropic geometric structures are discussed in depth with respect to the thermal displacement, thermal stresses and strain. The book deals with direct and inverse thermoelastic problems of different isotropic geometric bodies subjected to heating. Mathematical approach for thermoelastic problems may be of immense help for those students, researchers and teachers pursuing work on thermoelasticity.
