## Abstract Simplified formulas for first and second derivatives of the internal coordinates with respect to Cartesian coordinates are reported for linear and outโofโplane bending motion. They are expressed in a local coordinate system and then rotated to a spaceโfixed Cartesian coordinate system.
Numerical integration is widely used for the computation of stiness matrices in the ยฎnite element method (FEM). However, for simple cases such as the upright prismatic element such procedures are obviated by using an analytical method, thus reducing the computation burden. In this paper, the analyti
## Abstract This paper proposes a method for calculating the required changes in the physical properties of plates made of functionally graded materials (FGM) in order to achieve the desired eigenfrequency shifts in the structure. A finite element formulation based on the classical laminated plate
