It is known that in case of dynamic unbalanced processes the relaxation processes of grain refinement are intensified in the material, as well as their rotational shear or the creation of dissipative structures in the form of localized deformation bands
Whilst the localized deformation bands
were observed in the a-spheru-lites (see Fig.
1]) and deformation bands
Al-O-Si, Si-O-Si and Si-O, respectively (540 [cm.
in porous rocks are low-displacement deformed zones that increase cohesion and reduce porosity and permeability, and are commonly formed in a Riedel pattern (e.
The report presents the mathematical basis of the multifractal approach, summarizes studies on the effect of the material strain hardening and experimental noise which show that multifractal behavior exists in the unexplored range close to the low strain rate boundary of the PLC instability (where deformation bands
were believed to be uncorrelated), and uses these results to examine the overall pattern of the PLC effect at various strain rates.
131 "Regular" deformation bands
(DBs) and the LEDS hypothesis.
Closely spaced deformation bands
are also observed.
Different nylons can be distinguished by subtle differences in frequencies and intensities in the Amide III band between 1,260 and 1,280 cm-1, and in the symmetric methylene stretch and the methylene deformation bands
81 pa-o Attributes: 1st--distinguishable four bands 3695, 3670, 3650, 3620 2nd--general broadening of all bands is not observed 3rd--OH deformation bands
938 and 916 are visible 4th--two weak bands found at 795 and 758 are of about equal intensity [CI.
However, the difference is the coexistence of craze-like features and shear deformation bands
The OH deformation bands
of kaolinite are situated at 938 and 913 [cm.
A number of deformation modes were encountered during the scratch deformation process, including ironing, deformation bands
, crazing, tearing, microcracking, regular cracking, and grooving (24).
