This paper deals with a new computational method for transient dynamic analysis which enables one to cover both the low‐ and medium‐frequency ranges. This is a frequency approach in which the low‐frequency part is obtained through a classical technique while the medium‐frequency part is handled through the variational theory of complex rays (VTCR) initially introduced for vibrations. Preliminary examples are shown. Copyright © 2005 John Wiley & Sons, Ltd.
