Abstract : In terms of a complexvalued dependent variable the motion of a vibrating beam can be described by an operator closely resembling the heat equation. The resemblance is exploited by adapting to the vibrating beam equation formulas for a threeparameter family of twolevel implicit finite difference approximations to the heat equation. A stability analysis has been performed, and various options for increasing the order of the truncation error have been discussed. (Author)
