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

, 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.

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

, 2001
We examine the effects of optically thick line forces on orbiting circumstellar disks, such as occur around Be stars. For radially streaming radiation, line forces are only effective if there is a strong radial velocity gradient, as occurs, for example ...

Adhesion forces for water/oil droplet and bubble on coking coal surfaces with different roughness

International Journal of Mining Science and Technology, 2021
Surface roughness plays a significant role in floatability of coal. In the present paper, coking coal surface was polished by three different sandpapers and the surface properties were characterized by contact angle and roughness measurements. The effect

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

Mechanical 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

Comptes 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]

E3S 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.

Joint-line medialization after anatomical total shoulder replacement requires more rotator cuff activity to preserve joint stability

JSES International, 2021
Background: The biomechanical effects of joint-line medialization during shoulder surgery are poorly understood. It was therefore the purpose of this study to investigate whether medialization of the joint line especially associated with total shoulder ...

Experimental and numerical investigation of a taut-moored wave energy converter: a validation of simulated mooring line forces

, 2020
A reliable simulation model to calculate the motion and force responses of wave energy converters (WECs) is imperative to ensure the reliability and long-term performance of WEC systems; these aspects are fundamental to achieving full commercialisation ...

Stability Assessment of the Flexible System using Redundancy [PDF]

Journal of Applied and Computational Mechanics, 2020
In this study, dynamic behavior of a mooring line in a floating system is analyzed by probability approaches. In dynamics, most researches have shown the system model and environments by mathematical expression.
