Zonal differences in deformation characteristics of AZ31 Mg alloy constrained by heterogeneous metals

Journal of Materials Research and Technology, 2021
Under the temperature range of 200–400 °C and the strain rate of 0.01~1s−1, the microstructure evolution of AZ31B Mg alloy under the new hot constrained compression method compared with single compression test was studied by means of uniaxial compression

X-ray microtomographic characterization and quantification of the strain rate dependent failure mechanism in cenosphere epoxy syntactic foams [PDF]

, 2016
This work investigates the failure mechanism in cenosphere epoxy syntactic foams at the quasi-static and dynamic strain rates. Split-Hopkinson pressure bar experiments are controlled to stop dynamic deformation of the foams at various strain stages.

Deformation Mechanisms of Isotactic Poly-1-Butene and Its Copolymers Deformed by Plane-Strain Compression and Tension

Crystals, 2019
The deformation-induced crystalline texture of isotactic poly-1-butene and its random copolymers with ethylene, developing during plane-strain compression and uniaxial tension, was investigated with X-Ray pole figures, supported by small-angle scattering

Transverse deformation zonality values and palinspastic reconstructions of Carpathians on the base of structural analysis of folding

Геофизический журнал, 2022
On the basis of the structural analysis of folds the complex deformation profile in the Hust—Ivano-Frankivsk (central part of Ukrainian Carpathians) transsection is constructed. It characterises distribution of non-coaxial flow deformation on a spectrum

The Influence of the Degree of Tension and Compression of Copper on the Indentation Size Effect (ISE)

Crystals
The present work deals with the relationship between the degree of cold plastic deformation (up to 55.3% in the neck area in the tensile test and up to 66.6% in the compression test) and the parameters of the Indentation Size Effect (ISE).
