ABSTRACT
Rheology deals with the deformation and flow of any material under the influence of an applied stress. In practical applications, it is related with flow, transport, and handling any simple and complex fluids. It deals with a variety of materials from elastic Hookean solids to viscous Newtonian liquid. Any rheometric technique involves the simultaneous assessment of force, and deformation and/or rate as a function of temperature. Through the appropriate rheometrical equations, such basic measurements are converted into quantities of rheological interest, for instance, shear or extensional stress and rate in isothermal condition. In the early 1900s, research scientists were eagerly seeking rubber materials which could be manufactured artificially. Kuzma notes that the Russians prepared such a rubber, known chemically as polybutadiene. The flow behavior of a material in response to an applied stress varies depending on the composition of the material.
