What is strain energy?

Strain Energy

In a molecule, strain energy is released when the constituent atoms are allowed to rearrange themselves in a chemical reaction or a change of chemical conformation in a way that:

The basic concept may be easy to understand by recalling that a change in energy is equal to the causing force times the resulting displacement ... causing force is equal to the change in energy divided by the resulting displacement ...
Diffusionless Transformation - Classification and Definitions
... The first distinction can be drawn between transformations dominated by lattice-distortive strains and those where shuffles are of greater importance ... Homogeneous lattice-distortive strains, also known as Bain strains, are strains that transform one Bravais lattice into a different one ... This can be represented by a strain matrix S which transforms one vector, y, into a new vector, x This is homogeneous as straight lines are transformed to new straight lines ...

We calculate the elastic strain energy for a cubic crystal by estimating the work required to deform a slice of material so that it can be added coherently to an existing slab of cross-sectional area ... addition of the slab, it must be subjected to a strain δ in the z' and y' directions which is given by In the first step, the slice is deformed hydrostatically in order to produce the required strains to ...

Famous quotes containing the words energy and/or strain:

    The tendencies of the times favor the idea of self-government, and leave the individual, for all code, to the rewards and penalties of his own constitution, which work with more energy than we believe, whilst we depend on artificial restraints.
    Ralph Waldo Emerson (1803–1882)

    The Founding Fathers in their wisdom decided that children were an unnatural strain on parents. So they provided jails called schools, equipped with tortures called an education. School is where you go between when your parents can’t take you and industry can’t take you.
    John Updike (b. 1932)
