Accounting for tension in transverse bending of statically indeterminate elastic rods [PDF]

open access: yesE3S Web of Conferences, 2023
For statically indeterminate rod structures with excess constraints in the horizontal direction, tension forces arise under transverse loading, significantly affecting the stress-strain state of the rods compared to similar rods caused by bending alone ...

Seismic damage mechanism of slope and lining in the mountain tunnel portal section [PDF]

open access: yesE3S Web of Conferences, 2020
A series of numerical simulations were conducted to study the seismic response in the mountain tunnel portal section. The seismic damage mechanism, including slope cracking and landslide, rockfalls and collapse, and lining cracking were analyzed based on

THE EFFECT OF LONGITUDINAL VIBRATION ON LAMINAR FORCED CONVECTION HEAT TRANSFER IN A HORIZONTAL TUBE

open access: yesJournal of Engineering, 2006
The effect of longitudinal vibration on the laminar forced convection heat transfer in a horizontal tube was studied in the present work. The flow investigated is an internal, laminar, incompressible, developing, steady and oscillatory flow. The vibration vector was parallel to the fluid flow direction.

Independent formation of longitudinal forces in bent beams

open access: yesCommunications, 2000
This paper deals with the phenomenon of horizontal constraints being strutted by bent beams. This phenomenon takes place when rotating ends of beam sections encounter the resistance of horizontal constraints.

Shear design of HSC beams with combination of links and horizontal web steel [PDF]

open access: yes, 2005
The existing recommendations in Eurocode 2 and the British Code of Practice for the shear design of beams are derived from research conducted essentially on normal-strength concrete (NSC) with cube strengths up to 50 MPa, and it was found that the shear ...

Longitudinal beam dynamics studies with space charge in small isochronous ring

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2009
Studies of the longitudinal beam dynamics in the small isochronous ring (SIR) at Michigan State University revealed a fast, space-charge driven instability that did not fit the model of the negative mass instability.

Abrupt longitudinal magnetic field changes in flaring active regions [PDF]

open access: yes, 2010
We characterize the changes in the longitudinal photospheric magnetic field during 38 X-class and 39 M-class flares within $65^{\circ}$ of disk-center using 1-minute GONG magnetograms.
