The tightening of a fastener's screw thread is comparable to driving a wedge into a gap until it sticks fast through friction and slight elastic deformation.

According to the Flexible Surface Model, elastic deformation of the membrane bilayer is coupled to the conformational energetics of membrane proteins, including receptors and ion channels.
43.
Note that not all elastic materials undergo linear elastic deformation; some, such as concrete, gray cast iron, and many polymers, respond in a nonlinear fashion.
44.
However, " ? / " e is not zero in solid surface due do the fact that surface atomic structure of solid are modified in elastic deformation.
45.
:: See stress-strain curve : in theory, a material will undergo pure elastic deformation up to the yield point, then pure plastic deformation until failure.
46.
Loss of ductility occurs due to cracks maintaining sharp points due to suppression of elastic deformation by the hydrogen, and voids forming under tension due to decomposition of the hydride.
47.
The elastic modulus of an object is defined as the slope of its stress strain curve in the elastic deformation region : A stiffer material will have a higher elastic modulus.
48.
In 1949, Grubin obtained an approximate solution for so called elasto-hydrodynamic lubrication ( EHL ) line contact problem, where he combined both elastic deformation and lubricant hydrodynamic flow.
49.
With real-world materials, however, there's an overlap between plastic and elastic deformation .-- talk ) 01 : 30, 19 March 2014 ( UTC)

His book, " Non-Linear Elastic Deformations ", published in 1984 and reissued in 1999, has become a standard reference in this branch of solid mechanics.
