Transport and magnetic properties in YBaCo2O5.45: Focus on the high-temperature transition

open access: yes, 2007
The electronic transport properties and the magnetic susceptibility were measured in detail in $YBaCo_2O_{5.45}$. Close to the so-called metal-insulator transition, strong effects of resistance relaxation, a clear thermal hysteresis and a sudden increase

Combined shear/tension testing of fibre composites at high strain rates using an image-based inertial impact test

open access: yesEPJ Web of Conferences, 2018
Testing fibre composites off-axis has been used extensively to explore shear/tension coupling effects. However, off-axis testing at strain rates above 500 s-1 is challenging with a split Hopkinson bar apparatus.

Numerical Simulation on the specimen dynamic plastic deformation behaviour in the torsional split Hopkinson bar test

open access: yesEPJ Web of Conferences, 2018
The torsional split Hopkinson bar (SHB) is an important method to study the dynamic shear behaviour and shear localization of materials under high strain rates. Different specimen sizes were used in literatures, and the size of the specimen might have an

An analytical and experimental study of the behavior of semi-infinite metal targets under hypervelocity impact [PDF]

open access: yes
The material strength and strain rate effects associated with the hypervelocity impact problem were considered. A yield criterion involving the second and third invariants of the stress deviator and a strain rate sensitive constitutive equation were ...
