Abstract
More than three decades ago, Przemieniecki [l] introduced a formulation for the
free vibration analysis of bar and beam elements based on a power series of frequencies.
Recently, this formulation was generalized for the analysis of the dynamic
response of elastic systems submitted to arbitrary nodal loads as well as
initial displacements [2]. Based on the mode-superposition method, a set of coupled,
higher-order differential equations of motion is transformed into a set of uncoupled
second order differential equations, which may be integrated by means of
standard procedures. Motivation for this theoretical achievement is the hybrid
boundary element method [3,4], as developed in [2] for time-dependent problems
on the basis of a frequency-domain formulation, wh
