It is well known that for laminated composite plates a Levy-type solution exists only for cross-ply and antisymmetric angle-ply laminates. Numerous investigators have used the Levy method to solve the governing equations of various equivalent single-layer plate theories. It is the intension of the present study to introduce a method for analytical solutions of laminated composite plates with ar...

Laminated composite plates are widely used in modern structures. Resins of composites are almost made of polymers which show time dependent and and in some cases stress dependent behaviour. In this paper, a laminated composite plate is analysed using a multiscale method. At first, material properties of a lamina is obtained using an analytical micromechanical approach called simplified unit cel...

Experimental and theoretical approaches are studied via the first-ply failure strength on anti-symmetrically laminated composite elevated floor plates with various length-to-depth ratios, aspect ratios, and optimal fibre orientations subjected to central point loads. Optimal angle-ply orientations of anti-symmetric [θ/ − θ . . .]−S laminated composite plates designed for maximum stiffness were ...

In this research, the mutual influence of mechanical properties and geometric parameters on thermal stress distribution in symmetric composite plates with a quasi-rectangular hole subjected to uniform heat flux is examined analytically using complex variable technique. The analytical solution obtained based thermo-elastic theory Lekhnitskii’s method. Furthermore, by employing suitable mapping f...

This paper outlines an experimental investigation carried out for the analysis of failure mechanisms in fibrous laminated composite plates containing stress raisers, in the form of cutouts, under static biaxial planar compressive loadiing. A specially designed biaxial loadiing frame was used to test a series of 48 ply graphite/epoxy composite laminated plates with centrally located circular hol...

In this paper, the modified couple stress theory is used to study vibration analysis of functionally graded rectangular micro-plates. Considering classical and first order plate theories, the couple governing equations of motion are obtained by using the Hamilton’s principle. Considering an assumed mode method, the accurate size dependent natural frequencies are established for simply supported...
