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 that the Kelvin material has an elasticity and viscosity , and the Maxwell material has an elasticity and viscosity , the Burgers model has the constitutive equation
where is the stress and is the strain.

Comparison of creep and stress relaxation for three and four element models
This model incorporates viscous flow into the standard linear solid model, giving a linearly increasing asymptote for strain under fixed loading conditions.
