Mechanical behavior of the reinforced concrete frame with masonry filling Comportement mécanique des portiques en béton armé avec remplissage en maçonnerie

open access: yesMATEC Web of Conferences, 2018
Masonry is often used in the most of reinforced concrete structure constructions as a filling material that is important on structural characteristics. Structural contribution in the calculations was neglected or misunderstood, mainly due to the lack of ...

Binary Amplitude Reflection Gratings for X-ray Shearing and Hartmann Wavefront Sensors

open access: yesSensors, 2021
New, high-coherent-flux X-ray beamlines at synchrotron and free-electron laser light sources rely on wavefront sensors to achieve and maintain optimal alignment under dynamic operating conditions. This includes feedback to adaptive X-ray optics.

Interplay Between Stress and Reproduction: Novel Epigenetic Markers in Response to Shearing Patterns in Australian Merino Sheep (Ovis aries)

open access: yesFrontiers in Veterinary Science, 2022
In this study, we determined the effect(s) of early shearing on Australian Merino ewes (Ovis aries) and their lambs. To test this research question, we used a suite of field and laboratory methods including GPS collars, wool cortisol, and epigenetic ...

INFLUENCE OF SHEAR RATE ON THE SOIL'S SHEAR STRENGTH

open access: yesEnvironmental Engineering - Inženjerstvo okoliša, 2021
One of the most important mechanical properties is shear strength. It is conditioned by the value of the maximum shear stress that the soil can withstand before failure. Exceeding the shear strength causes one particle to slide next to another, causing the failure of soil.

Effect of constraint of sheet material on successful range of blanking conditions and cut surface in push-back blanking

open access: yesNihon Kikai Gakkai ronbunshu, 2015
The cut surface obtained by blanking has burrs, whose occurrence should be prevented. Push-back blanking is one of the burr free blanking methods. This method was consists of two stages.

Shear-banding and microstructure of colloids in shear flow [PDF]

open access: yesFaraday Discussions, 2002
We shall discuss the following phenomena found in various colloidal systems in shear flow. We recently observed shear-banding in suspensions of fd-virus in a cylindrical shear cell. Small angle light scattering experiments revealed that the shear-banding transition is preceded by a relatively fast process (minutes) of nematic-to-paranematic phase ...
