Rheology refers to the flow behaviour and deformation of matter.

Many substances have qualities of solids (elasticity) and liquids (viscosity) alike, which are described in rheological models. Depending on the conditions of the experiment, they can elastically dampen external influences on shorter time scales but react with plastic flow on longer ones. This is referred to as viscoelastic behaviour.
