Elasticity (physics)

physical property when materials or objects return to original shape after deformation

empirical physical law of mechanics that the force on a spring is proportional to its displacement

parameter of elastic materials: ratio of transverse strain to axial strain

mechanical property that measures stiffness of a solid material

In the case shown here, the weight of the forward fuselage structure ahead of the nose undercarriage is sufficient to cause the panels to buckle. Buckled panels are still effective in carrying shear by diagonal tension. thumb|On the front of a new Siemens Venture railway coach made of stainless steel, unevenness caused by buckling becomes apparent because of the reflection on the polished surface.

Viscoelasticity is a material property that combines both viscous and elastic characteristics. Many materials have such viscoelastic properties, especially materials that consist of large molecules. Polymers are viscoelastic because their macromolecules can make temporary entanglements with neighbouring molecules which causes elastic properties. After some time these entanglements will disappear again and the macromolecules will flow into other positions where new entanglements will be made (viscous properties).
