What is viscoelastic in the human body?
In other words, cells, tissues, and organs have a mix of viscous and elastic responses when submitted to mechanical forces and this viscoelastic response is part of their main physiological role. It will deform with the force and it will slowly return to its original state after the force is removed.
What is meant by viscoelastic?
Definition of viscoelastic : having appreciable and conjoint viscous and elastic properties such viscoelastic materials as asphalt also : constituting or relating to the state of viscoelastic materials viscoelastic data viscoelastic properties.
What is viscoelastic effect?
In materials science and continuum mechanics, viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when undergoing deformation. Viscous materials, like water, resist shear flow and strain linearly with time when a stress is applied.
What is muscular viscoelasticity?
A MATERIAL’S ABILITY TO DAMP MOVEMENT BY BECOMING STIFFER AT HIGHER RATES OF ELONGATION.
How is viscoelasticity measured?
In industries such as biomaterials, viscoelasticity is often measured by applying a sinusoidal force, calculating the resulting strain response and determining the elastic-spring-like storage modulus and the flow-like loss modulus. Such dynamic mechanical analysis can be performed as a bench test or deployed in-situ.
What is viscoelasticity in biomechanics?
2 Viscoelasticity. Viscoelasticity is the time-dependent anelastic behaviour of materials. This means that the response to a stimulus is delayed, and there is a loss of energy inside the material. Viscoelastic behaviour normally occurs at different time scales (relaxation times) in the same material.
Why do we need viscoelasticity?
Almost all of biological tissues are viscoelastic and their viscoelastic mechanical properties are important in their characteristic functions. This is because constituents of tissues cells, extracellular matrices, structural proteins, and so on are viscoelastic. Even hard tissues have been shown to be viscoelastic.
What is viscosity of muscle?
Muscle viscosity is the rate at which your muscles perform demands. Secretion of synovial fluid and lubrication of the muscle inhibit the muscle from reacting too quickly by slowing the contraction; this prevents tearing as the muscle seeks to lift the load.
How do you test viscoelasticity of a polymer?
The durometers commonly used for testing the viscoelastic materials (polymers or rubber) are Shore hardness meters. These ones determine the indentation depth in the material caused by a spring loaded rigid indenter. The rigidity is measured in Shore’s units.
