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.

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 ...

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.

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.

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 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 ...

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.

Temperature effect on shear correction factor

Mechanics Research Communications, 1991
In 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.

Shear correction factors for plates and shells

International Journal for Numerical Methods in Engineering, 1992
AbstractMultilayered 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
