Interaction potential for silicon carbide A
The proposed three-body interaction potential is a modification of the Stillinger-Weber form proposed to describe Si. Using the molecular dynamics method the interaction potential is used to study structural elastic and dynamical properties of crystalline (3C) amorphous and liquid states of SiC for several densities and temperatures.

Rubber elasticityWikipedia
Rubber elasticity refers to a property of crosslinked rubber it can be stretched by up to a factor of 10 from its original length and when released returns very nearly to its original length. This can be repeated many times with no apparent degradation to the rubber. Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and
