## Abstract Expressions involving products of exponential functions and polynomials are encountered in the finite element formulation of the diffusionβconvection equation. Integrals of such expressions over finite elements are necessary to derive the element matrices. The derivation of the formula

The paper deals with the "nite element method (FEM) solution of the problem with loads moving uniformly along an in"nite Euler beam supported by a linear elastic Kelvin foundation with linear viscous damping. Initially, the problem is formulated in a moving co-ordinate system following the load usin
The area co-ordinate method has been successfully applied to construct triangular elements. In this paper, this method is generalized to construct quadrilateral elements, and the area co-ordinate theory for quadrilateral elements is systematically developed: (i) the area co-ordinates (L 1 , L 2 , L
## Abstract It is well known that the finite element discretization with a distributed mass matrix gives overstimates of the natural frequencies of a system. The note shows that these do not necessarily become progressively worse as the frequency increases.
