Shear stress correction factors in hybrid composite material beams
Composites, 1978Abstract 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 ...

Shear correction factors and an energy-consistent beam theory
International Journal of Solids and Structures, 1999By matching exact shear stress resultants and shear strain energy with those of the equivalent shear deformation theory, the authors give a derivation of new shear correction factors for a beam. Additionally, they derive exact warping functions from available elasticity solutions.

Shear correction factors for plates and shells
International Journal for Numerical Methods in Engineering, 1992AbstractMultilayered plate and shell finite elements usually have a constant shear distribution across the thickness. This causes a decrease of accuracy, especially for sandwich structures. The problem is overcome by using shear correction factors which are defined by energy considerations. In this paper a study on shear correction factors is presented

On Shear Correction Factor in Vibration of Annular Sector Plates
ASME 2010 10th Biennial Conference on Engineering Systems Design and Analysis, Volume 2, 2010In the present study, the shear correction factors are obtained for annular sector plates using Differential Quadrature (DQ) Method. Based on the three-dimensional elasticity theory, the governing equations of motion for an annular sector plate are obtained.

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 ...

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
