rheologicznych

Rheologicznych is an inflected form of the Polish adjective rheologiczny, meaning related to rheology. It is used in reference to properties, measurements, and phenomena associated with the flow and deformation of matter. The term derives from Greek roots rheo- (flow) and -logia (study). In Polish technical language, forms such as właściwości rheologiczne or badania rheologiczne appear in discussions of materials science and related fields.

Rheology is the branch of science that studies how substances deform and flow under applied stresses, and how this behavior changes with time, temperature and other conditions. Key concepts include viscosity (resistance to flow), viscoelasticity (combined viscous and elastic response), and time-dependent phenomena such as creep and relaxation. Materials can be Newtonian, with constant viscosity, or non-Newtonian, with viscosity depending on shear rate or time. Common rheological behaviors include shear thinning (pseudoplasticity), shear thickening (dilatancy), thixotropy (structure breakdown under shear), and rheopexy (structure buildup with time). Constitutive models—such as Newtonian, Bingham, Herschel–Bulkley, and power-law (Ostwald–de Waele)—describe these behaviors through parameters determined by experiments.

Applications span polymers, paints and coatings, foods, cosmetics, gels, soils, and construction materials. Rheology informs processing, quality control, stability, texture, and performance in products and systems. Measurements are performed with rotational or capillary rheometers, oscillatory tests to obtain storage and loss moduli (G' and G''), and temperature-controlled protocols to reflect real-world conditions.
