Only a small group of fluids exhibit such constant viscosity. Rheology generally accounts for the behavior of non-Newtonian fluids, by characterizing the minimum number of functions that are needed to relate stresses with rate of change of strain or strain rates. An introduction to rheology barnes pdf of theoretical rheology is concerned with associating external forces and torques with internal stresses and internal strain gradients and flow velocities.

The study of the physics of continuous materials with a defined rest shape. Describes materials that permanently deform after a sufficient applied stress. The study of materials with both solid and fluid characteristics. The study of the physics of continuous materials which deform when subjected to a force.
