Rheology
1 Meaning
Study of: Flow of Matter
Type of Matter: In Liquid State (including Soft Solids)
Soft Solids: Solids respond with
Plastic Flow & not Elastically
Situation: in response to applied force or stress
Stress: Restoring force generated within the matter in response to the applied deforming force.
Pressure: Externally applied mostly relevant to fluids
2 Friction
(force that tends to oppose motion)
St./Dy. Friction.
Solid - Solid
Drag
Solid - Fluid
Viscosity
Fluid - Fluid
Resistance
Creating Electricity
3 Laws
Hook's Law
For elastic material the force is directly proportional to the extension
An elastic material returns to its original form when unloaded after it loading it within its elastic limit
Newton's law of viscosity
The shear stress is proportional to the velocity gradient across the layer of the fluid.
Proportionality between stress (a.k.a. shear stress) & deformation, i.e. continuous flow of fluids (velocity gradient).
