Rheology is a general theory of relations between tension, deformation and rate of deformation in real materials. It comes out from the elasticity theory of solids and from the theory of viscous liquids. The straight line between solids and liquids is made vague in rheology what is expressed in the Greek slogan "panta rei" This slogan "panta rei - all flows" is reflected in the name "Rheology" of the new discipline Main terms The expressions tension, deformation and rate of deformation will be thoroughly studied. The large deformation tensor will be also introduced and the necessity of distinguishing between non-deformed and deformed states in the theory of large deformations will be emphasized. Rheological classification of materials The main categories of materials will be given: Hook`s (classical elastic) material, Newton`s and non-Newton`s viscous liquids, viscoelastic materials, plastic materials. The graphic models of these materials will be introduced. It will be also shown how more complex rheological materials may be described by combination of these simple models. Rheological behaviour of special materials This part of the lecture may be modified due to the speciality of students who will attend it. Originally, it has been prepared for students of polymer science. But it is possible to devote it also to the study of biomaterials, i. e. to biorheology, to the study of non-Newtonian liquids and their technological treatment. For several years it has been taught for postgraduate students of geophysics and geology. |
