Thermoelasticity is one of the streams in Science where the concepts and ideas in Physics, Mathematics and Engineering are extensively used. The fruitful interactions and applications between these branches have led to many technological advancements. This book deals with the concept of thermoelasticity which finds its roots and application in the above branches. Thermal response of few circular and rectangular geometrical structures subjected to different boundary and heating conditions are discussed here. Thermal stresses and strains under thermal variations and different heating conditions are elaborated. Topics discussed here should be helpful to students and researchers pursuing work on thermoelasticity.
