✦ Synopsis

A new finite strip method is applied to the vibration of rectangular plates with complicated boundary and internal support conditions. Based on the classical thin plate theory and displacement formulation, the new finite strip element is conforming with C1-continuity. The displacement function of the strip element is expressed as the product of cubic Hermitian functions in the transverse direction and a set of computed static modes in the longitudinal direction. By means of a continuous beam computer program, these longitudinal modes can be computed a priori. Numerical examples are given to demonstrate the versatility, accuracy and efficiency of the element.

Drs Cheung and Kong are to be congratulated for their excellent paper and for the very useful, new finite strip element that they have developed [1]. In view of the excellent accuracy achieved by the authors, it is quite possible that the fundamental frequency coefficient of a square plate with ste

The spline finite strip method which has long been applied to the vibration analysis of bare plate has been extended in this paper to stiffened plates having arbitrary shapes. Both concentrically and eccentrically stiffened plate have been analyzed. The main elegance of the formulation lies in the t

In this paper, the free vibrations of a wide range of non-uniform rectangular plates in one or two directions are considered. The domain of the plate is bounded by x = a 1 a, a and y = b 1 b, b in rectangular co-ordinates. The thickness of the plate is continuously varying and proportional to the po
