Behavior of a VE liquid can be illustrated using the combination of a spring and a dashpot in serial connection (see Figure 5.1). Both components can be deflected independently of each other. The spring model shows Hookean behavior as described in Chapter 4.3.1b, and the dashpot model displays Newtonian behavior as explained in Chapter 2.3.1b. The model was named in honor to James C. Maxwell (1831 to 1879), who first presented the corresponding mathematical fundamentals (in 1867/1868, in the form of a differential equation; see also Chapter 14.2: 1855) [5.1] [5.2]. H. Freundlich used the (German) term Fließelastizität (literally: flow elasticity), in order to indicate to anomalities in the flow behavior, and others spoke of elastoviscous liquids [5.23] [5.24].
