Their blood equivalent, hemolymph, forms a viscoelastic fluid that covers wounds.

“We can also simulate toothpaste. Here the Newtonian viscosity dominates material behaviour.” (A material point method for viscoelastic fluids, foams and sponges)

“While the Oldroyd-B model is traditionally used for viscoelastic fluids, we show that its interpretation as a plastic flow naturally allows us to simulate a wide range of complex material behaviors. In order to do this, we provide a modification to the traditional Oldroyd-B model that guarantees volume preserving plastic flows.“

“We design our discretization from the upper convected derivative terms in the evolution of the left Cauchy-Green elastic strain tensor. We combine this with an Oldroyd-B model for plastic flow in a complex viscoelastic fluid.”
