Burgers material

A Burgers material is a viscoelastic material which consists of a Maxwell material and a Kelvin material in series. It is named after the Dutch physicist Johannes Martinus Burgers.

Given four rheological constants $a_1$ , $a_2$ , $a_3$ , and $a_4$ , the Burgers model has the constitutive equation

\sigma + a_1\dot{\sigma} + a_2\ddot{\sigma} = a_3\gamma + a_4\dot{\gamma}

where $\sigma$ is the stress and $\gamma$ is the rate of deformation.^[1]
