Abstract
Rheology is the branch of physics in which we study the way in which materials deform or flowin response to applied forces or stresses. The material properties that govern the specific way in which these deformation or flow behaviors occur are called rheological properties. The Greek philosopher and scholar, Heraclit (550–480 BC) once said “πάντα p ɛĩ” (“everything flows”). In the context of physics, “flow” can be defined as continuous deformation over time, and it can be said that all materials can flow. Therefore the ability to flow is not only possessed by gases and liquids, but also by solids to a varying degree. Indeed, we all know examples of solids which are capable of continuous deformation over time (flow), like asphalt on a road surface after long term usage. It is also evident that temperature can have a strong influence on the ability of materials to flow. For example, the asphalt road surface will deform at a faster rate when carrying traffic during time periods of elevated temperatures.
