Three dimensional flutter analysis of a rectangular sheet based on the unsteady lifting surface theory and wind-tunnel experiments

Nihon Kikai Gakkai ronbunshu, 2016
This paper presents a three-dimensional flutter analysis of a rectangular sheet in an axial fluid flow. The unsteady fluid force acting on the sheet surface is calculated using Doublet-point method based on the unsteady lifting surface theory.

Differences in kinematics, kinetics, and muscle activity between underwater dolphin kicking and flutter kicking: multiple approaches using three-dimensional motion analysis, electromyography, and hydrodynamic simulation

Sports Biomechanics
It is well-known among swimmers and coaches that the swimming speed of the underwater dolphin kick (UDK) is higher than that of the underwater flutter kick (UFK). This study aimed to clarify the differences in swimming performance between the two kicking styles in terms of kinematics, kinetics and muscle activity.

MULTI-MODE FLUTTER ANALYSIS AND TWO & THREE DIMENSIONAL MODEL TESTS ON BRIDGES WITH NON-ANALOGOUS MODAL SHAPES

Doboku Gakkai Ronbunshu, 1993
Coupled flutter of non-analogous vertical and torsional modes, which may typically occur in mono-cable suspension or single plane cable-stayed bridges, for example, and multimode flutter including higher modes are studied both analytically and experimentally.
