Effect of Slenderness Ratio on Free-to-Roll Wing Aerodynamics

Journal of Aircraft, 2011
M ANNED fighter aircraft and unmanned combat air vehicles may require high angle-of-attack maneuvers where the roll dynamics become crucial. Small unmanned air vehicles (UAVs) and fixed-wingmicro air vehicles often have separated flows [1,2]. These small vehicles fly at relatively high angles of attack and close to the stall conditions due to the poor ...

Thermoelectric device and optimum external load parameter and slenderness ratio

Energy, 2010
Abstract Thermodynamic formulation of efficiency of thermoelectric power generator is presented in terms of the slenderness ratio ( X = ( A p / L p ) / ( A n / L n ) ) and the external load parameter ( Y = ( R L ) / ( L n / k e , n A

Slenderness ratio distribution and load-shortening behaviors of stiffened panels

Marine Structures, 2012
Abstract This paper evaluates the distributions of three slenderness ratios of the plates, the stiffeners, and the stiffened panels, and presents a comparison of the load-shortening behaviors of the stiffened panels. The slenderness ratios, which represent the geometry and material properties of the stiffened panels, are obtained from deck and bottom

Low-strain integrity testing of drilled piles with high slenderness ratio

Computers and Geotechnics, 2006
Abstract A low strain integrity test is adopted to assess the quality of cast-in situ reinforcement concrete piles with high slenderness ratios. The disadvantage of traditional NDT equipment and signal post-process is that it cannot detect and interpret any structural faults that exist in long bored piles with high slenderness ratios.

Slenderness ratio of telescopic cylinder-columns

Structural Engineering and Mechanics, 2001
The present paper deals with the effective slenderness ratio of telescopic cylinders as a long column having different cross sections. Firstly, the slenderness ratio defined in the current standard for the telescopic cylinders is discussed to point out some difficulties which arise when the ratio is applied to the column having different cross sections.

Slenderness ratio effect on cracked beam

Journal of Sound and Vibration, 1992
Abstract It is well known that in vibrating cracked beams and shafts, coupling of bending and torsional vibration exists, due to the non-diagonal terms of the local compliance matrix. This phenomenon becomes more important as the slenderness ratio decreases.

Effect of Slenderness Ratio of the Specimen on Resonant Column Test Results

, 2020
To investigate the effect of the slenderness ratio (L/d) of the specimen, resonant column (RC) tests were conducted on dry sand specimens by using three different values of L/d, namely 2, 3, and 4, keeping the same diameter (d = 50 mm) to measure the ...

Bracket Loaded Webs with Low Slenderness Ratios

Engineering Journal, 1985
Welded bracket connections to the web of rolled sections are common connections. However, the AISC Manual of Steel Construction has no guidelines for estimating their capacity. Generally, the maximum load corresponds to the development of a two-dimensional yield mechanism in the web; but for sections whose webs have significant thickness relative to ...

Comparing Hysteretic Behavior of Flexible Piers with Different Stirrup Ratio and Slenderness Ratio

Advanced Materials Research, 2011
Flexible piers have been widely used in bridge engineering due to its superior ductility. The stirrup ratio and slenderness ratio were deemed to have a most important impact on hysteretic behavior of them. Five flexible piers were made under static vertical loads and low cyclic horizontal reversed loads.
