2.2 Thermoelasticity
... In this section, thermoelasticity is considered. By definition, the constitutive relations for such a material depend only on the set of field variables F, , Grad . This general case will be considered toward the end of this section. Simpler cases, isothermal F , smallstrain ε, one-dimension ...

First law of thermodynamics
... State functions are characterized by the idea that no matter what path you take to get from point A to point B, the difference between B and A remains the same. An example of how this works can be illustrated using gravitational potential energy. Say you lift a box 5 meters vertically straight up in ...
