Elastic fibers stain well with aldehyde fuchsin, orcein, [16] and Weigert's elastic stain in histological sections.. The permanganate-bisulfite-toluidine blue reaction is a highly selective and sensitive method for demonstrating elastic fibers under polarizing optics.
Elastic fiber in the body is a mixture of amorphous elastin and fibrous fibrillin. Both components are primarily made of smaller amino acids such as glycine , valine , alanine , and proline . [ 11 ] [ 14 ] The total elastin ranges from 58 to 75% of the weight of the dry defatted artery in normal canine arteries. [ 15 ]
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 both shear flow and strain linearly with time when a stress is applied.
Resilin is an elastomeric protein found in many insects and other arthropods. It provides soft rubber-elasticity to mechanically active organs and tissue; for example, it enables insects of many species to jump or pivot their wings efficiently.

The SI unit for elasticity and the elastic modulus is the pascal (Pa). This unit is defined as force per unit area, generally a measurement of pressure , which in mechanics corresponds to stress . The pascal and therefore elasticity have the dimension L −1 ⋅M⋅T −2 .
Elastic constants are specific parameters that quantify the stiffness of a material in response to applied stresses and are fundamental in defining the elastic properties of materials. These constants form the elements of the stiffness matrix in tensor notation, which relates stress to strain through linear equations in anisotropic materials.
Elastic proteins provide the property of elasticity which gives the spring the ability to bend reversibly without the loss of energy, and the ability to bend to large strains with small force. [3] Elastic proteins also contain high resilience and low stiffness which helps with the function of elastic strain energy.
