Analysis of the Mechanical and Thermal Buckling of Laminated Beams by New Refined Shear Deformation Theory

Iranian Journal of Science and Technology - Transactions of Civil Engineering, 2020
Thermo-mechanical buckling analysis of symmetric and antisymmetric laminated composite beams is performed based on a refined simple nth higher-order shear deformation theory. The theory accounts for the parabolic distribution of the transverse shear strains and satisfies the zero traction boundary conditions on the surfaces of the beam without using ...

Refined hyperbolic shear deformation plate theory

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2014
The paper presents a novel shear deformation plate theory involving only two variables. Taking a cue from exact three-dimensional theory of elasticity solutions for a plate, hyperbolic functions are used for describing displacement variation across plate thickness.

Refined shear deformation theory of laminated shells

AIAA Journal, 1993
This paper presents a refined approach for studying the effect of shear deformation in thick laminated anisotropic shells. The authors develop some theoretical preliminaries for a laminated composite shell with \(N\) perfectly bonded homogeneous anisotropic elastic layers.

Refinement of shear theory of laminar orthotropic sloping shells

Soviet Applied Mechanics, 1988
In the present work, refinement of the shear theory is proposed. A second-approximation model is proposed, allowing this effect to be described on the basis of an approach invariant with respect to the number of layers in the system and allowing the distortion of the normal in the course of shell deformation to be taken into account.

Analytical solution of a refined shear deformation theory for rectangular composite plates

International Journal of Solids and Structures, 1987
The Lévy type solution procedure in conjunction with the state-space concept is used to determine the deflections and stresses for symmetric laminated composite plates with rectangular geometries by using a refined shear deformation theory. Combinations of simply supported, clamped and free boundary conditions are considered.

A Refined Shear Deformation Plate Theory

International Journal for Computational Methods in Engineering Science and Mechanics, 2011
An improved higher-order shear deformation theory of plates is presented in this paper. The theory is developed from the transverse shear deformation theory presented by Ambartsumian [11]. The present plate theory contains kinematics of higher-order displacement field of plates, a system of higher-order differential equilibrium equations in terms of ...

A Review of Refined Shear Deformation Theories for Isotropic and Anisotropic Laminated Beams

Journal of Reinforced Plastics and Composites, 2001
A review of displacement and stress based refined theories for isotropic and anisotropic laminated beams is presented. Various equivalent single layer and layerwise theories for laminated beams are discussed together with their merits and demerits. Exact elasticity solutions for the beam problems are cited, wherever available.

Refining the stress state of multilayer shells using finite-shear theory

Soviet Applied Mechanics, 1987
There is still an urgent need to develop a theory for the calculation of multilayer shells distinguished by simplicity of the formulas and equations and yet taking account of the specific deformational features of operation of the given structure. The present work outlines a method allowing the results for the theoretical stress in multilayer shells ...
