CHAPTER 5:  The Elastic Solid and Elastic Boundary Value Problems

 Constitutive equation is the relation between kinetic (stress, stress-rate) quantities and kinematic (strain, strain-rate) quantities for a specific material. It is a mathematical description of the actual behavior of a material. The same material may exhibit different behavior at different temperatures, rates of loading and duration of loading time.). Though researchers always attempt to widen the range of temperature, strain rate and time, every model has a given range of applicability.

 Constitutive equations distinguish between solids and liquids; and between different solids. 

In solids, we have:  Metals, polymers, wood, ceramics, composites, concrete, soils…

In fluids we have:  Water, oil air, reactive and inert gases
