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 ...

Experimental validation of the shear correction factor

Journal of Sound and Vibration, 2003
The use of resonant beam technique in determining the elastic moduli of isotropic materials is discussed. Both the shear and the rotary inertia perturb the classical one dimensional Euler-Bernoulli theory for the flexural vibrations of elastic beams and lead to a shift of the resonance frequencies.

Effective stress vane shear strength correction factor correlations

Canadian Geotechnical Journal, 1994
A 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.

Closed-Form Expressions of Shear Correction Factor for Functionally Graded Beams

Journal of Applied Mechanics, 2023
Abstract 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.

Static shear correction factor for laminated rectangular beams

Composites Part B: Engineering, 1996
Most practical analyses of laminated composite beams, particularly rectangular sections used in civil structures, are based on first order shear deformation theories (FSDT), which generally require shear correction factors to account for shear stiffness and transverse shear stress.

Transverse shear correction factors for laminates in cylindrical bending

Communications in Numerical Methods in Engineering, 1995
AbstractMindlin‐type plate and shell finite elements are the most widely used ones in the analysis of laminated composite structures. In the commercially available finite element programs, the transverse shear correction factors for these elements are usually the same as for structures made of isotropic materials.

Shear correction factors and an energy-consistent beam theory

International Journal of Solids and Structures, 1999
By 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.
