Nonlinear transient thermoelastic analysis of functionally graded ceramic-metal plates
G. N. Praveen,J. N. Reddy +1 more
TL;DR: In this paper, the static and dynamic response of the functionally graded material (fgm) plates are investigated by varying the volume fraction of the ceramic and metallic constituents using a simple power law distribution.

A higher-order shear deformation theory of laminated elastic shells
J. N. Reddy,C.F. Liu +1 more
TL;DR: In this article, a higher-order shear deformation theory for elastic shells was developed for shells laminated of orthotropic layers, which is a modification of the Sanders' theory and accounts for parabolic distribution of the transverse shear strains through thickness of the shell and tangential stress-free boundary conditions on the boundary surfaces.

Theories and Finite Elements for Multilayered Plates and Shells:A Unified compact formulation with numerical assessment and benchmarking
TL;DR: Theories and finite elements for multilayered structures have been reviewed in this article, where the authors present an extensive numerical evaluation of available results, along with assessment and benchmarking.

Theories and Finite Elements for Multilayered, Anisotropic, Composite Plates and Shells
TL;DR: In this article, an overview of available theories and finite elements that have been developed for multilayered, anisotropic, composite plate and shell structures is presented. But, although a comprehensive description of several techniques and approaches is given, most of this paper has been devoted to the so called axiomatic theories and related finite element implementations.

Stability and vibration of isotropic, orthotropic and laminated plates according to a higher-order shear deformation theory
J. N. Reddy,N.D. Phan +1 more
TL;DR: In this article, a higher-order shear deformation theory is used to demonstrate the natural frequencies and buckling loads of elastic plates, which accounts for parabolic distribution of the transverse shear strains through the thickness of the plate and rotary inertia.

Exact solutions for rectangular bidirectional composites and sandwich plates
TL;DR: In this article, three-dimensional elasticity solutions for rectangular laminates with pinned edges are constructed for three dimensional elasticity problems, including a sandwich plate, and compared to the analogous results in classical laminated plate theory.

Shear Deformation in Heterogeneous Anisotropic Plates
James M. Whitney,N. J. Pagano +1 more
TL;DR: In this article, a bending theory for anisotropic laminated plates developed by Yang, Norris, and Stavsky is investigated, which includes shear deformation and rotary inertia in the same manner as Mindlin's theory for isotropic homogeneous plates.
Journal ArticleDOI
Elastic wave propagation in heterogeneous plates
TL;DR: In this paper, a two-dimensional linear theory of motions of heterogeneous plates is deduced from the three-dimensional theory of elasticity, which is specialized to cases of symmetrically laminated aeolotropic, orthotropic and isotropic plates.

Elastic Behavior of Multilayered Bidirectional Composites
N. J. Pagano,Sharon J. Hatfield +1 more
TL;DR: In this paper, the authors consider the response of multi-ply laminates with a view toward examining the generality of previous conclusions regarding the range of validity of the approximate theory normally used in the analysis of these bodies, namely, classical laminated plate theory.

Improved numerical integration of thick shell finite elements
Stuart F. Pawsey,Ray W. Clough +1 more
TL;DR: In this article, a selective integration scheme for evaluating the stiffness matrix of a quadratic thick shell element was proposed, in which each component of the strain energy was evaluated separately using a different Gaussian integration grid for each contribution.
