What is a good viscoelastic material to use? They give off the energy absorbed as heat. Viscoelastic materials are used for isolating vibration, dampening noise, and absorbing shock. What are uses of a viscoelastic material?
Purely elastic materials do not dissipate energy (heat) when a load is applied, then removed however, a viscoelastic substance does. Because viscoelastic materials have the viscosity factor, they have a strain rate dependent on time. The difference between elastic materials and viscoelastic materials is that viscoelastic materials have a viscosity factor and the elastic ones don’t. Elastic behavior versus viscoelastic behavior In some applications, even a small viscoelastic response can be significant. Synthetic polymers, wood, and human tissue, as well as metals at high temperature, display significant viscoelastic effects. Viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when undergoing deformation.
For example, warm syrup flows more easily than cold. Since heating reduces viscosity, these materials don't flow easily. Viscous materials are thick or sticky or adhesive. Water is a low viscosity material, as it flows readily. High viscosity materials might include honey, syrups, or gels – generally things that resist flow. For example, water flows more easily than syrup because it has a lower viscosity. A fluid with large viscosity resists motion. Viscosity is a measure of a fluid’s resistance to flow. When the forces are removed, the object will return to its initial shape and size if the material is elastic. Elasticity is the tendency of solid materials to return to their original shape after forces are applied on them.
