The Mitc7 and Mitc9 Plate Bending Elements

We present in this paper two plate bending elements that have been proposed and mathematically analyzed previousIy by Bathe, Brezzi and Fortin: the MITC7 (a triangular) element and the MITC9 (a quad~late~l) element. The formation of these elements is summarized and example solutions are given that demonstrate the high accuracy of these elements. 1. lNTRODUCHON Although much research effort has ...

Analysis of Laminated Soft Core Sandwich Plate Having Interfacial Imperfections by an Efficient C0 FE Model

An efficient C0 continuous two dimensional (2D) finite element (FE) model is developed based on a refined higher order shear deformation theory (RHSDT) for the static analysis of soft core sandwich plate having imperfections at the layer interfaces. In this (RHSDT) theory, the in-plane displacement field for the face sheets and the core is obtained by superposing a globally varying cubic displa...

Finite Element Analysis of Free Vibration of the Delaminated Composite Plate with Variable Kinematic Multilayered Plate Elements

Composite laminates are prone to delamination. Implementation of delamination in the Carrera Unified Formulation frame work using nine noded quadrilateral MITC9 element is discussed in this article. MITC9 element is devoid of shear locking and membrane locking. Delaminated as well as healthy structure is analysed for free mode vibration. The results from the present work are compared with the a...

Optimization and Parameter Estimation in Smart Viscoelastic Laminated Sandwich Structures

Recent developments on the optimization and parameter estimation in hybrid active-passive composite sandwich structures are presented. For this purpose, a mixed layerwise finite element model has been formulated, by considering a higher order shear deformation theory to represent the displacement field in the viscoelastic core and a first order theory for the displacement fields of the adjacent...

A Numerical and Analytical Solution for the Free Vibration of Laminated Composites Using Different Plate Theories

An analytical and numerical solution for the free vibration of laminated polymeric composite plates with different layups is studied in this paper. The governing equations of the laminated composite plates are derived from the classical laminated plate theory (CLPT) and the first-order shear deformation plate theory (FSDT). General layups are evaluated by the assumption of cross-ply and angle-p...
