The Notion of State and Its Implications in Thermodynamics of Inelastic Solids
A definition of state based on the observable histories of displacement gradients, temperature, internal energy and stress is introduced. When the state space is finite dimensional, thermomechanical behavior of the material in the range of finite deformations can be represented by differential equations. The nature of this representation and the restrictions placed upon it by the second law of thermodynamics are discussed.
