Strengthening of damping properties after initial plastic deformation: static and dynamic tests

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2023
The effect of the initial plastic deformation on the damping properties of low-carbon steel is experimentally studied, which corresponds to a change in the deformation diagram. The deformation diagram also refers to hysteresis loops that expand after the

Plastic deformation mechanism of hypoid gears

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2017
Hypoid gears are used as the final reduction gear of vehicles to transmit and change direction torque. Plastic deformation of a hypoid gear tooth flank occurs when a load exceeding the yield stress acts on the tooth surface.

Detection of plastic strain using GNSS data of pre- and post-seismic deformation of the 2011 Tohoku-oki earthquake

open access: yesEarth, Planets and Space, 2020
In general, there are three mechanisms causing crustal deformation: elastic, viscous, and plastic deformation. The separation of observed crustal deformation to each component has been a challenging problem.

Phasons and the plastic deformation of quasicrystals [PDF]

open access: yesThe European Physical Journal B - Condensed Matter, 2003
The plastic deformation of a quasicrystal (QC) is ruled by singularities of its 'phonon' strain field and of its 'phason' strain field. In the framework of the topological theory of defects, and the QC being defined as an irrational subset of a high dimensional crystal, both types of defects appear as distinct components of the same entity, a ...
