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 ...

Calculation of interlaminar shear stresses in laminated shallow shell panel using refined higher order shear deformation theory

Composite Structures, 2015
Abstract In general, calculation of inter-laminar shear stresses in laminated shells using 2D finite element models involves cumbersome post processing techniques. This paper presents a simple and efficient method for accurate evaluation of transverse shear stresses in laminated composite shallow shells by using a displacement based C0 2D FE model ...

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 ...

Refined First-Order Shear Deformation Theory Models for Composite Laminates

Journal of Applied Mechanics, 2003
In the present work, new mixed variational formulations for a first-order shear deformation laminate theory are proposed. The out-of-plane stresses are considered as primary variables of the problem. In particular, the shear stress profile is represented either by independent piecewise quadratic functions in the thickness or by satisfying the three ...

A Refined Shear Deformation Theory of Bending of Isotropic Plates*

Mechanics of Structures and Machines, 1994
ABSTRACT A nonlinear, in-plane displacement assumption is proposed, based on an undetermined variation df/dz of transverse shear strains through the plate thickness. A second-order ordinary differential equation for f(z) and two surface conditions, as well as a set of eighth-order partial differential equations and four associated boundary conditions ...

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 ...
