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

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 Thin-Walled Composite Boxbeam Considering Nonclassical Behaviors

Journal of Composite Materials, 1996
In this study, shear correction factor for thin-walled composite boxbeam is investigated with considering the anisotropic coupling effects in its laminated walls parallel to the external shear load. We first consider a generally orthotropic laminated beam whose cross section is rectangular. The beam does in-plane shear deformation by the applied shear

Correction factors for loss estimation of sound propagation over high shear speed seabeds

The Journal of the Acoustical Society of America, 2023
Modelling range dependent sound propagation over layered elastic seafloors with high shear speeds has proved to be a difficult problem for many widely used under water acoustic sound propagation models. The geologic evolution of large portions of the Australian continental shelf result in it being a commonly occurring problem for sound propagation ...

On Shear Correction Factor in Vibration of Annular Sector Plates

ASME 2010 10th Biennial Conference on Engineering Systems Design and Analysis, Volume 2, 2010
In 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.

EHL Circular Contact Film Thickness Correction Factor for Shear-Thinning Fluids

Journal of Tribology, 2008
An extensive set of full elastohydrodynamic lubrication point contact simulations has been used to develop correction factors to account for the effect of shear-thinning lubricant behavior on the central and minimum film thickness in circular contacts under pure rolling condition. The film thickness for a shear-thinning lubricant can be easily obtained

Influence of shear correction factors in the higher order shear deformation laminated shell theory

International Journal of Solids and Structures, 1994
Abstract 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.

Thermo-elastic effects on shear correction factors for functionally graded beam

Composites Part B: Engineering, 2017
Abstract 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,

Influence of Shear Correction Factors on Eigenfrequencies of Layered Plates

2018
In 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 ...
