Line Forces in Keplerian Circumstellar Disks and Precession of Nearly Circular Orbits [PDF]

open access: green, 2001
We examine the effects of optically thick line forces on orbiting circumstellar disks, such as occur around Be stars. For radially streaming radiation (e.g., as from a point source), line forces are effective only if there is a strong radial velocity ...

The elastodynamic Li\\'enard-Wiechert potentials and elastic fields of\n non-uniformly moving point and line forces [PDF]

open access: green, 2012
The purpose of this paper is to investigate the fundamental problem of the non-uniform subsonic motion of a point force and line forces in an unbounded, homogeneous, isotropic medium in analogy to the electromagnetic Li\'enard-Wiechert potentials.

Long fluid filled bags suspended by line forces [PDF]

open access: green, 1975
A previous analysis of fluid filled storage bags is extended to the case of a long fluid filled cylindrical membrane supported by uniform line loads.

Study on a grinding force model of a variable grinding contact area during knife-edge surface grinding [PDF]

open access: yesMechanical Sciences, 2023
​​​​​​​In the context of non-standard blade geometries of knife-like tools with tapered cutting edges where the width of the blade surface varies with feed, there is limited research on predicting grinding forces considering the changing contact line. To

Irreducible representation of surface distributions and Piola transformation of external loads sustainable by third gradient continua

open access: yesComptes Rendus. Mécanique, 2023
In this paper Piola transformations are found that relate the Eulerian and Lagrangian external loads which third gradient continua can sustain. As shown by Gabrio Piola and Paul Germain, the most effective postulation scheme in mechanics is based on the ...

The stress state analysis of lattice tower support for 330 kV overhead line using the “USL” software package [PDF]

open access: yesE3S Web of Conferences, 2023
In conditions of market economy, overhead power transmission line (OPTL) support structures must be low-cost and of guaranteed quality, the manufacture of which will require a minimum amount of steel.
