The removal rate equation under plastic deformation
satisfies V = [K.sub.1] x P x [H.sup.-1] x L and under crack deformation satisfies V = [K.sub.2] x [P.sup.5/4] x [H.sup.-1/2] x [T.sup.-3/4] x L.

Localised plastic deformations
were researched at deformation states within interval [beta] = (-1/2;0).
Our functional of energy are the evaluations of the field of plastic deformation
considering the quantity of energy of liberated plastic deformation
by the specimen for unit of time [DELTA]G = [GAMMA]t, in the generated dislocations in the specimen under the regimens of quasi-relaxation.
Using the finite element method, the numerical model has been developed enabling to predict the behaviour of deformation zones during car impact loads that cause major plastic deformations
in the case of damaged deformation zone elements.

effect on microscopic elastic limit of copper and nickel.
can be one of the sneakier wear patterns to deal with.
Since tissue tearing is obviously not desirable, the stretch should produce either elastic extension or plastic deformation
. When there is elastic extension the stretching produces a temporary elongation, which is good when the subsequent running is of relatively short duration and takes place soon after the stretching session.
(2) LSCM (or a high-resolution optical microscopy) is used to characterize the resulting surface deformation and identify the "onset" of plastic deformation
. (3) Constant force scratch tests are conducted over a range of forces in the vicinity of the onset of plastic deformation
In the investigated materials, material transfer and plastic deformation
were identified as predominant wear mechanism under unlubricated sliding conditions.
All curves had an initial expansion (upward movement of TDC) before plastic deformation
(downward movement of TDC).
