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, specially the heavy engineering field. Thermoelastic behavior of different geometric structures are discussed in depth with respect to the temperature distribution, thermal stresses. The Book deals with direct and inverse thermoelastic problems of different geometric solid. Mathematical approach for thermoelastic problems may be of immense help for those students, researcher and teacher pursuing work on thermoelasticity.
