In this study, the buckling response of homogeneous circular plates with variable thickness subjected to radial compression based on the first-order shear deformation plate theory in conjunction with von-Karman nonlinear strain-displacement relations is investigated. Furthermore, optimal thickness distribution over the plate with respect to buckling is presented. In order to determine the distr...

Based on the differential transformation method, a semi-analytical solution is developed for free vibration and modal stress analyses of variable thickness two-directional functionally graded circular plates with restrained edges, resting on elastic foundations. Variations of the material and geometry parameters are monitored by five distinct exponential functions. The presented non-dimensional...

Fast remaining thickness measurement using Lamb wave is presented for the purpose of maintenance of large structures like oil storage tanks and pipe networks. This study used a laser ultrasonic source to perform a high resolution remote scanning over aluminum plates with grooved and circular defects that were modeled on corrosions in plate-like structures. The antisymmetric A0 and symmetric S0 ...

the current study presents a new analytical method for buckling analysis of circular plates with constant thickness and poisson’s ratio, made of functionally graded material subjected to radial load. governing equations are based on energy method for thin plates. the boundary conditions of the plate are assumed to be simply supported and clamped. the stability equations were obtained by using c...

In this paper, experimental responses of the clamped mild steel, copper, and aluminium circular plates are presented subjected to blast loading. The GMDH-type neural networks (Group Method of Data Handling) are then used for the modelling of the mid-point deflection thickness ratio of the circular plates using those experimental results. The aim of such modelling is to show how the mid-point de...

The present study adds to the knowledge of free vibration antisymmetric angle-ply annular circular plates with variable thickness for simply supported boundary conditions. differential equations in terms displacement and rotational functions are approximated using cubic spline approximation. A generalized eigenvalue problem is obtained solved numerically an eigenfrequency parameter associated e...
