elastic strain
elastic deformation

The two threshold values for the elastic strain energy and are derived from experimental data.

This is 'elastic strain'; deformation that goes away when the load does.

They want to become straight again and have a lot of elastic strain to get rid of.

The working hypothesis is that pressure changes indicate a change in the elastic strain within the formation (Davis et al., 2006).

This comes from the relation between and the elastic strain energy of distortion :

This stress launches an elastic strain pulse that propagates into the sample.

An earthquake is caused by the release of stored elastic strain energy during rapid sliding along a fault.

A complete description of internal elastic strain requires that all these crystallographic parameters be measured.

From this work Griffith formulated his own theory of brittle fracture, using elastic strain energy concepts.

A drawback of the criterion is that elastic strain energy densities are small and comparatively hard to derive.

Additional contributions to the driving force by e.g. elastic strains or temperature gradients are neglected.

Elastic strain changes the width of these bands, the angles between them plus a general rotation of the entire pattern.

(b) The elastic strain increment is given by Hooke's law:

It then follows that the total elastic strain energy of a slab of cross-sectional area A is given by:

Where δ is the Kronecker delta and e is elastic strain tensor.

Surface stresses normally calculated by calculating the surface free energy and its derivative with respect to elastic strain.

Local deformation and elastic strain are negligibly affected by this long-range divergence in relative displacement.

On the other hand, for stress levels higher than , plastic strain becomes progressively larger than elastic strain.

This represents an elastic strain or interatomic separation of about 1.0 per cent, perhaps between a tenth and a twentieth of the theoretical strength.

Bending the spaghetti strand increases the elastic strain until, at a weak point somewhere along the strand, it exceeds the limit.

But there is more to the famous kangaroo hop: kangaroos and wallabies have a unique ability to store elastic strain energy in their tendons.

This causes elastic strains in the lattice, and the direction of magnetization that minimizes these strain energies will be favored.

Ignoring the small elastic strain in the concrete between the cracks, we can relate the crack width to the strain of the member by:

Better "damage tolerance" behaviour (especially impact and metal fatigue, as the elastic strain is larger than other metal material it can consume more impact energy.

Tectonic earthquakes occur anywhere in the earth where there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane.
