Cyclic Simple Shear Size Effect Correction Factors
Journal of Geotechnical Engineering, 1987A 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 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 ...

Analytical Solutions for Static Shear Correction Factor of Functionally Graded Rectangular Beams
Mechanics of Advanced Materials and Structures, 2012Most practical analyses of functionally graded beams, particularly in aerospace, aircraft, automobile, and civil structures, are based on the first-order shear deformation theory. However, a key factor in practical application of the theory is determination of the transverse shear correction factor, which appears as a coefficient in the expression for ...

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 ...

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 ...

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.

Thermo-elastic effects on shear correction factors for functionally graded beam
Composites Part B: Engineering, 2017Abstract Functionally Graded Materials (FGMs) have been used as advanced structures in high temperature regions for excellent thermal barriers. In this regard, present study considers the compensation of the shear stress effects in thermal environments to be more crucial than conventional evaluation. As the beam model with thermo-mechanical behavior,

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

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 ...

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.
