Viscoelastic Behavior

Viscoelatic Behaviour

When a force is applied to a viscous fluid, it will start to deform and this deformation is proportional with the magnitude of force applied. It deforms continuously until the force is removed so that it cannot return to its original position. Viscous fluids generally exhibit viscosity while solids exhibit elasticity. Some foods show both viscous and elastic properties which are known as viscoelastic materials. The typical food example for viscoelastic fluids is wheat flour dough. Dairy cream,...
