Abstract
A finite element free vibration analysis of beams on a two-parameter elastic foundation is performed using the exact shape functions. The stiffness matrix and the mass matrix are deduced in closed form for the whole parameter range. Numerical comparisons and examples allow us to check the performance of the proposed finite element.
