In situ hydromechanical responses during well drilling recorded by fiber-optic distributed strain sensing [PDF]

open access: yesSolid Earth, 2020
Drilling fluid infiltration during well drilling may induce pore pressure and strain perturbations in neighbored reservoir formations. In this study, we report that such small strain changes (∼20 µε) have been in situ monitored using fiber-optic ...

Peculiarities of the dynamics of a viscous liquid with a free boundary under periodic influences [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика
Purpose of the work is revealing and researching of peculiarities of a motion of a viscous liquid having a free boundary and undergoing periodic in time influences which are characterized by the absence of a predominant direction in space. Methods.

Differential Hydro-Mechanical Transmissions with Hydrostatic Units

open access: yesCommunications, 2005
At present, hydromechanical transmissions are used especially in agricultural and defence vehicles. These transmissions have potential to be used also in other vehicles, for example commercial cars and buses.

Mode Shifting in Hybrid Hydromechanical Transmissions

open access: yes, 2015
Demands for low cost sustainable solutions have increased the use of and interest in complex hydromechanical transmissions for heavy off-road vehicles. In transmissions with multiplemodes, an important condition is to maintain the tractive force during ...

A hydromechanical approach for anisotropic elasto-viscoplastic geomaterials: Application to underground excavations in sedimentary rocks

open access: yesUnderground Space, 2019
To better describe excavation operations in deep geological formations, several aspects should be considered, especially the material anisotropy, time-dependent behavior, and hydromechanical coupling.

Heavy-weight concrete with increased early strength

open access: yesMagazine of Civil Engineering, 2023
Production process rate is the most important thing in industrial engineering of concrete and reinforced concrete products, which heavily depends on duration of concrete handling strength development.

MODELING OF HYDROMECHANICAL DRIVE SYSTEM OF WORKING BODY FOR MOBILE TECHNOLOGY MACHINE

open access: yesAdvanced Engineering Research, 2014
An element of the working body (brush) of the aerodrome sweeper – a synchronous hydromechanical drive – is considered. It is based on the throttle flow divider of the non-spool type plunger setters, and it is driven by two hydraulic motors.

Microengineered hydromechanical cochlear model [PDF]

open access: yesProceedings of the National Academy of Sciences, 2005
Micromachined fluid-filled variable impedance waveguides intended to mimic the mechanics of the passive mammalian cochlea have been fabricated and experimentally examined. The structures were microfabricated with dimensions similar to those of the biological system.

Discontinuous hydromechanical modelling of concrete dam foundations [PDF]

open access: yes, 2020
The analysis of the hydromechanical behaviour of concrete dam foundations requires coupled models which account for the role of deformation in fluid flow and the stability of the rock mass. In this study the hydromechanical analysis is performed by means
