Flutter and forced response of mistuned rotors using standing wave analysis [PDF]

open access: yes, 1983
A standing wave approach is applied to the analysis of the flutter and forced response of tuned and mistuned rotors. The traditional traveling wave cascade airforces are recast into standing wave arbitrary motion form using Pade approximants, and the ...

Theoretical analyses of growth mechanism of rail corrugation

open access: yesNihon Kikai Gakkai ronbunshu, 2019
Rail corrugation is a phenomenon in which roughness patterns of approximately regular wavelengths are formed on the rail running surface by trains running, and causes the vibration and the noise.

Stress formulation of elastic wave motion [PDF]

open access: yesJASA Express Letters, 2021
Propagation of elastic waves in anisotropic solids is solved through a pure stress formalism. The stress solutions lead to the three wave solutions expected from the displacement formulation plus three non-propagating stresses with zero wave speed which ...

Wave (Current)-Induced Pore Pressure in Offshore Deposits: A Coupled Finite Element Model

open access: yesJournal of Marine Science and Engineering, 2018
The interaction between wave and offshore deposits is of great importance for the foundation design of marine installations. However, most previous investigations have been limited to connecting separated wave and seabed sub-models with an individual ...

Pancake sea ice kinematics and dynamics using shipboard stereo video

open access: yesAnnals of Glaciology, 2020
In the marginal ice zone, surface waves drive motion of sea ice floes. The motion of floes relative to each other can cause periodic collisions, and drives the formation of pancake sea ice.

Extraction of the significant wave height from synthetic HF radar data acquired on a floating platform

open access: yesIET Radar, Sonar & Navigation, 2023
The usual procedure for extracting ocean surface information from data acquired from a high‐frequency surface wave radar transmitting from a floating platform is to first compensate for the motion of the antenna in the acquired motion‐contaminated ...

Ship Trajectory Generator under the Interference of Wind, Current and Waves

open access: yesSensors, 2022
In view of the low accuracy of the motion parameters generated by the typical ship trajectory generator, and the fact that the problem of wind, current and wave interference is not considered, this paper establishes a new ship trajectory generator by ...
