Shear deformable dynamic stiffness elements for a free vibration analysis of composite plate assemblies - Part I: Theory
(Elsevier Ltd, 2017)
A procedure for developing the dynamic stiffness matrix of a completely free laminated composite plate based on the first-order (FSDT) and higher-order shear deformation theory (HSDT) is presented. The proposed method ...
Free vibration analysis of spatial Bernoulli–Euler and Rayleigh curved beams using isogeometric approach
(Elsevier Inc., 2019)
This paper deals with the linear free vibration analysis of Bernoulli–Euler and Rayleigh curved beams using isogeometric approach. The geometry of the beam as well as the displacement field are defined using the NURBS basis ...
Thermal buckling of laminated composite plates using layerwise displacement model
(Elsevier Ltd, 2016)
In this paper thermal buckling of laminated composite plates, based on Layerwise Theory of Reddy and new version of Layerwise Theory of Reddy, presented for the first time, are formulated using the principle of virtual ...
Layerwise solution of free vibrations and buckling of laminated composite and sandwich plates with embedded delaminations
(Elsevier Ltd, 2014)
Layerwise plate theory of Reddy, extended for the analysis of delaminations, has served as a basis for development of enriched finite elements. The proposed model assumes layerwise linear variation of in-plane displacements ...
An improved analysis of free torsional vibration of axially loaded thin-walled beams with point-symmetric open cross-section
(Elsevier Inc., 2016)
The objective of the paper is to analyze the influence of bimoment induced by constant axial loads on the free motion of thin-walled beams with point-symmetric open cross-section. For various boundary conditions, a closed-form ...
Generalized plasticity model for inelastic RCFT column response
(Elsevier Ltd, 2016)
This paper presents a nonlinear 3d concentrated plasticity beam column element for the analysis of RCFT columns. The element consists of a linear elastic component with a plastic hinge at each end whose inelastic response ...
Section Discretization of Fiber Beam-Column Elements for Cyclic Inelastic Response
(Journal of Structural Engineering-Asce, 2012)
The paper presents studies of the effect of the number of material integration points at the monitored sections of fiber beam-column elements on the local response of typical structural cross sections under an extensive ...
Free vibration analysis of stiffened and cracked laminated composite plate assemblies using shear-deformable dynamic stiffness elements
(Elsevier Ltd, 2017)
In the paper, the dynamic stiffness method based on the HSDT and FSDT plate theories is applied to study free vibration characteristics of composite stiffened and cracked plate assemblies. The dynamic stiffness matrices ...
Free vibration study of sandwich plates using a family of novel shear deformable dynamic stiffness elements: limitations and comparison with the finite element solutions
(Elsevier Ltd, 2016)
In this paper, the dynamic stiffness matrix of a completely free rectangular multi-layer plate element based on Reddy's higher-order shear deformation theory is derived. The reduction of the proposed model to the first-order ...
Shear deformable dynamic stiffness elements for a free vibration analysis of composite plate assemblies - Part II: Numerical examples
(Elsevier Ltd, 2017)
The dynamic stiffness elements based on the HSDT and FSDT (and the corresponding dynamic stiffness matrices of a laminated composite plate) have been implemented into the original MATLAB code, and a variety of numerical ...
