This model can be regarded as an extension of the upper-convected Maxwell model and is equivalent to a fluid filled with elastic bead and spring dumbbells.
The model is named after its creator James G. Oldroyd. The model can be written as: where: T is the deviatoric part of the stress tensor; λ 1 is the relaxation time; λ 2 is the retardation time = η s η 0 λ 1 ; T ∇ is the upper-convected time derivati
