In the 1960s, he utilized magnetic resonance imaging to pursue a fundamental study of the behavior and motion of defects and impurities in solids, an effort that culminated in his 1972 book, "Point Defects and Diffusion", still the definitive source in this field.
In this paper, fatigue failure is investigated by studying the collective motion of defects inside a NiTi shape memory alloys material.
The microscopic mechanism of shock wave propagation in solids is inherently complex because the plastic flow is governed by the creation and motion of defects in the deformation of nanoscale materials.
In this study recovery leading to continuous recrystallization was examined by both X-ray line broadening and measurement of activation volumes at 78 K as a function of isochronal anneals to characterize the recovered structure wherein non-conservative motion of defects is not possible.
Kaneko studied the pattern formation on the transition route from torus to chaos, revealing rich spatiotemporal dynamics such as frozen random pattern, Brownian motion of defect, defect turbulence, pattern competition intermittency, fully developed turbulence, and so on [36].
There are also extended periods of alternating antiphase synchronization among oscillators and cyclic motions of defects between phases.
It may be useful to reword the classic seven wastes identified by Toyota (waste of overproducing, waste of waiting, waste of transport, waste of processing, waste of inventory, waste of motion, waste of defects and spoilage) in more appropriate terminology for clinical use.
The deformation occurs through the generation and motion of line defects, called dislocations, on slip planes spaced only a few hundred atom diameters apart.
The motion of extended defects in solids is the key to understanding many important physical phenomena.
Internal friction refers to damping caused by the irreversible motion of crystallographic defects (for example, vacancies, divacancies, interstitial atoms, substitutional atoms, surface adatoms, edge dislocations, screw dislocations, grain boundaries, phase boundaries, layer boundaries, and precipitates) [4], and each type of defect can give rise to several mechanisms of dissipation [5].
