The Generalizedgeneralized Maxwell model, also known as the Wiechert model, is the most general form of the linear model for viscoelasticity. It takes into account that the [[Relaxation time|relaxation]] does not occur at a single time, but at a distribution of times. Due to molecular segments of different lengths with shorter ones contributing less than longer ones, there is a varying time distribution. The Wiechert model shows this by having as many spring–dashpot Maxwell elements as necessary to accurately represent the distribution. The figure on the right shows the generalised Wiechert model.<ref name=Roylance>Roylance, David (2001); "Engineering Viscoelasticity", 14–15</ref>
Applications: metals and alloys at temperatures lower than one quarter of their absolute melting temperature (expressed in K).
