This paper presents the free vibration analysis of a variable stiffness composite laminate (VSCL) square plate with circular cutout. Although the h-version of the finite element method is quite attractive, it could not be used in the VSCL plate. This is due to the difficulties associated with the inter-element continuity for the curvilinear fibre a...

A hierarchical finite element is developed for the free vibration analysis of a liquid in a rigid cylindrical tank with or without a free surface. It is a hierarchical quadrilateral element and has the advantage that the hierarchical mode number is allowed to vary independently of direction. Liquid behavior in tanks with large aspect ratios can the...

This paper is concerned with the dynamic behavior of the rotating composite shaft on rigid bearings. A p-version, hierarchical finite element is employed to define the model. A theoretical study allows the establishment of the kinetic energy and the strain energy of the shaft, necessary to the result of the equations of motion. In this model the tr...

The h-p version of the finite element method (FEM) is considered to determine the transient temperature distribution in functionally graded materials (FGM). The h-p version may be regarded as the marriage of conventional h-version and p-version. The graded Fourier p-element is used to set up the two-dimensional heat conduction equations. The temper...

The functionally graded materials (FGM) applications in engineering become more and more important in the future. The FGMs are composite materials where the microstructures are locally varied. The composition and the volume fraction of FGMs constituents vary gradually, giving a non uniform microstructure with continuously graded macro properties. D...
