The present study focused mainly on the vibration analysis of composite laminated plates subjected tothermal and mechanical loads or without any load (free vibration). Natural frequency dynamicresponse are analyzed by analytical, numerical experimental (by using impact hammer) fordifferent cases. investigation is to manufacture laminates find mechanicaland thermal properties glass-polyester suc...

This work addresses nonlinear finite element analysis of laminated structures with weak interfaces. Considered first are shallow laminated beams subject to arbitrary large displacements, small layer strains and moderate interface slippage. Under these requirements rigorous development of layer-wise kinematic field is performed assuming First order Shear Deformation Theory (FSDT) at the layer le...

Abstract The stability behaviour of unsymmetrical laminated structures made fibre-reinforced plastics is significantly influenced by bending–extension coupling and the comparatively low transverse shear stiffnesses. aim this work to improve analytical analysis unsymmetrically structures. With discrete plate theory, can be reduced single plates. structure divided into individual segments, surrou...

Once a structure comes into service, the most important concern is its ability to keep providing steady and safe service. Assessment of structural health is a tool that can be used to ensure such. However, most of the available evaluation strategies in structural health monitoring are labor intensive such as visual inspection, which is highly economically inefficient, especially for large scale...

Hygrothermal analysis of laminated composite plates has been done by using an efficient higher order shear deformation theory. The stress field derived from hygrothermal fields must be consistent with total strain field in this type of analysis. In the present formulation, the plate model has been implemented with a computationally efficient C0 finite element developed by using consistent strai...

This paper investigated the vibration of a printed electronic laminated membrane subjected to pretension and air resistance in thermal environments. First, mathematical model for moving is established, which considers inhomogeneity tension at both ends membrane. The equilibrium governing differential equation obtained according classical laminate plate theory Hamilton’s principle. quadrature me...

The motivation for the present study stems from the importance of delamination buckling as a viable mode of failure in laminated composite plates. This part of the study focuses on the prediction of the buckling loads and modes of unilaterally constrained rectangular plates. The laminated plates were modeled along the lines of classical lamination plate theory. Due to the out-of-plane thickness...

A Trigonometric Shear Deformation Theory (TSDT) for the analysis of isotropic plate, taking into account transverse shear deformation effect as well as transverse normal strain effect, is presented. The theory presented herein is built upon the classical plate theory. In this displacement-based, trigonometric shear deformation theory, the in-plane displacement field uses sinusoidal function in ...

In the first part (Lebée and Sab, 2010a) of this two-part paper we have presented a new plate theory for out-of-plane loaded thick plates where the static unknowns are those of the Kirchhoff-Love theory (3 inplane stresses and 3 bending moments), to which six components are added representing the gradient of the bending moment. The new theory, called Bending-Gradient plate theory is an extensio...
