Abstract
This article extends a procedure that has been used to discretize the static physical system following the assumption that a continuous flexible beam can be replaced by a system of rigid bars and joints which resists relative rotation of the attached bars. We call this procedure "The Discrete Element Response of Beams". The object of this article is to present and formulate a new simple, practical and inexpensive approximate technique for determining the time response of beams, with different boundary conditions, carrying a moving mass.

To verify the results, other solutions are obtained by continuous simulation systems and dynamic finite element. This algorithm is shown to be much more efficient computationally.
