Reology is part of physics and technology that, even though they are present in our body and is a great unknown in a majority of the things we use every day. In an intuitive way it can be said that Reology is part of physics that, in materials that can flow, study the relationship between effort and distortion. The properties linked to this reaction are called reological properties. The word flow here means a continuous distortion over time. Something that shows, in addition to some complex liquids and gases, also solids. The glass of the cathedrals, with a few centuries, is currently currently thicker at the bottom than in the upper. It is an experimental demonstration that the glass has liquid from top to the lower part due to the functioning of gravity. It is a slow process that was possible to verify experimental, because some windows are a few centuries. Scientists define reology as part of continuous media assanics that tries to find component (complex) comparisons that can model the behavior of materials.
Of all the reological properties that study the behavior of the liquids that are subject to mechanical taxes, there is a viscosity that we could call fundamental. It can be said that it is a size for the resistance of a material to flow. In some cases, for example in the stained glass that we mention earlier, the creep is interesting, which is the distortion that is experienced by a material that is undergoing a slow load. In this case, gravity. The relaxation time can also be crucial, which is the time that the liquid needs to acquire a new state of balance or to restore the initial recovery when a force stops action. All these properties vary with the temperature and with the type of applied power: shift, torsion or voltage. Insight into the reological properties helps to model the behavior of materials. Because it is electricity, for example, the movement of the lava of the volcano of the island of La Palma determines when it stops, regardless of whether it reaches the sea, which will be the height, depending on the lava source, etc.
A large number of materials that we use or that exist in nature have reological properties. For example, paintings and coatings, food and drinks, pharmaceutical products, cosmetics and creams in general, agrochemical products, large particle dispersions, cement, minerals and a very long, etc. For his relationship with our body we will call biooreology that is dedicated to studying the power of spanning and distortion. A branch of biorology is a aamrhology, whose goal is the study of blood flow in interaction with its environmental environment, both in macro and in microcirculation.
