On the derivation of an asymptotically correct shear correction factor for the Reissner-Mindlin plate model

Comptes Rendus de l'Académie des Sciences - Series I - Mathematics, 1999
Abstract In the framework of thin linear elastic plates it is known that the solutions of both the three-dimensional problem and the Reissner-Mindlin plate model can be developed into asymptotic expansions. By comparing the particular asymptotic expansions with respect to the half-thickness ɛ of the plate in the case of periodic boundary conditions

EHL Circular Contact Film Thickness Correction Factor for Shear-Thinning Fluids

Journal of Tribology, 2008
An extensive set of full elastohydrodynamic lubrication point contact simulations has been used to develop correction factors to account for the effect of shear-thinning lubricant behavior on the central and minimum film thickness in circular contacts under pure rolling condition. The film thickness for a shear-thinning lubricant can be easily obtained

Shear Correction Factors for Thin-Walled Composite Boxbeam Considering Nonclassical Behaviors

Journal of Composite Materials, 1996
In this study, shear correction factor for thin-walled composite boxbeam is investigated with considering the anisotropic coupling effects in its laminated walls parallel to the external shear load. We first consider a generally orthotropic laminated beam whose cross section is rectangular. The beam does in-plane shear deformation by the applied shear

A viscosity correction factor for shear-thinning liquid flows in safety valves

Journal of Loss Prevention in the Process Industries, 2010
At the moment there is lack in the existing standards of a sizing procedure for media of more complex rheological behavior than Newtonian. A formulation for the generalized Reynolds number to calculate the viscosity correction factor and size safety valves for the flows of shear-thinning media is proposed in this work.

Shear Correction Factors for Laminated Plates

AIAA Journal, 1979
S HEAR deformations are considered in laminated plate theory in terms of correction factors ktj (or k-j) and modified shear stiffnesses K^ — k^A^ = k-jA^; (ij = 4,5), where AJJ (or A-J) are obtained from assumed "constant strain (or stress)" fields.1 This work reports the correction factors, obtained by matching cutoff frequencies for propagation of ...

Cyclic Simple Shear Size Effect Correction Factors

Journal of Geotechnical Engineering, 1987
A comprehensive experimental study has been completed to study the effect of specimen size on the cyclic properties of dry sand: namely, the shear modulus and damping in a large‐scale simple shear apparatus. The tests were performed on three different specimen diameters, 3, 6, and 12 in., while the specimen height varied from 0.25–4 in.

Shear correction factors for corrugated core structures

Composite Structures, 2007
Because of the high computational cost involved when modeling a corrugated panel (in e.g., finite element analyses) the corrugated core sandwich is in this investigation homogenized and the panel is transformed to an equivalent continuous homogenous layer with effective equal properties.

Shear stress correction factors in hybrid composite material beams

Composites, 1978
Abstract Values of the static shear stress correction factors, k 1 , for hybrid, fiber-reinforced composite beams are calculated using a mechanics of materials approach developed by Bert [1]. These values of k 1 are input into the deflection relationships resulting from classical laminated plate theory, which has been extended by Whitney [2] to ...
