affine deformation

affine deformation

[ə′fīn ‚dē·fȯr′mā·shən]
(geology)
A type of deformation in which very thin layers slip against each other so that each moves equally with respect to its neighbors; generally does not result in folding.
(mapping)
A deformation in which the scale along one axis, or reference plane, is different from the scale along the other axis, or plane, normal to the first.

Silicon oil and PTFE tape were used for lubrication during the testing allowing for affine deformation throughout the experiment, which is explained in more detail in previous work by our group [33],
An affine deformation assumes that the crosslinks are fixed in space at positions defined by the overall specimen ratio.
Under affine deformation, the deformation of connecting microchannels is in proportion to the bulk material.
Upon application of a stress, low levels of deformation can occur simultaneously throughout the length of the sample, resulting in affine deformation.
Samules quantitatively calculated the spherulite deformation of isotactic polypropylene (iPP) using small angle light scattering (SALS), they stated the deformation of iPP in hot drawing is the affine deformation (25).
The continuum approach generally assumes affine deformation and thus, is incapable of describing the dispersion mechanism.
Here the true stress is defined by the instantaneous force divided by the crossectional area calculated assuming affine deformation approximation based on gauge separation.
The starting point for understanding the deformation behavior of rubber is the kinetic theory of rubber elasticity, assuming affine deformation and random walk, phantom chain (Gaussian) statistics.

This type of deformation has been called pseudoaffine, to distinguish from the affine deformation scheme of rubber elasticity.
To overcome this problem, we have recalculated the interfacial area evolution by making the assumption of no deformation/stretching during foldings and affine deformation during stretchings.
