Closed-Form Expressions of Shear Correction Factor for Functionally Graded Beams
Journal of Applied Mechanics, 2023Abstract In this work, closed-form expressions of shear correction factor (SCF) have been derived for beams with functionally graded material (FGM), through variational asymptotic method (VAM). An energy equivalence approach has been adopted between VAM and Timoshenko model, for estimating the SCF.

Temperature effect on shear correction factor
Mechanics Research Communications, 1991In spite of development of higher-order shear deformation theories (HSDT), the first-order shear-deformation theory (FSDT) remains a relatively simple and reliable tool for estimation of displacements, buckling loads and frequencies of composite structures.

The shear correction factor in the geometrically nonlinear theory of Timoshenko shells
Doklady Physics, 2002The necessity of considering transverse shears in the problems of beam bending was first recognized by Timoshenko [1]. On the basis of the virtual work principle, the Timoshenko’s theory was extended in [2] to the case of isotropic plates. In order to take into account a nonuniformity in the distribution of transverse shears over cross sections of a ...

Effective stress vane shear strength correction factor correlations
Canadian Geotechnical Journal, 1994A recent effective stress model of vane shear strength testing in soils can relate measured torques to vane shear strengths using theoretical analysis in terms of effective stress parameters. The strength estimates are based on known in situ stresses and soil parameters derived from laboratory testing.

Influence of Shear Correction Factors on Eigenfrequencies of Layered Plates
2018In this paper layered composite plates subjected to static loading are considered. The theory is based on a multi-field functional, where the associated Euler–Lagrange equations include besides the global plate equations formulated in stress resultants, the local in-plane equilibrium in terms of stresses and a constraint which enforces the correct ...

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

Influence of shear correction factors in the higher order shear deformation laminated shell theory
International Journal of Solids and Structures, 1994Abstract A third-order shell theory based on Reddy's parabolic shear strain distribution is presented. Upon applying the Donnell shallow shell approximation, the present theory leads to Reddy's formulation in the case that the laminate has a Euclidean middle surface and constant principal radii of curvatures.

A Posteriori Estimates for the Shear Correction Factors in Multi‐layered Composite Cylinders
Journal of Engineering Mechanics, 1989A predictor-corrector approach is presented for calculating the composite shear correction factors and analyzing multilayered composite cylinders. In the predictor phase a two-dimensional first-order shear deformation theory is used to predict the gross response characteristics of the cylinder (vibration frequencies, average through-the-thickness ...

A viscosity correction factor for shear-thinning liquid flows in safety valves
Journal of Loss Prevention in the Process Industries, 2010At 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.

A GENERALIZED METHOD FOR SHEAR CORRECTION FACTORS OF ARBITRARY THIN-WALLED SECTIONS
2023Shear deformation may significantly affect the structural behaviours, especially for the structural members with small span-to-depth ratios. It is vital to consider the shear effects in the Direct Analysis Method (DAM) of thin-walled structures such that only the section capacity check is required in the evaluation of both member and system stability ...
