Abstract
The complex envelope displacement vectorization (CEV) is a new procedure to solve high frequency vibration and vibroacoustic problems, alternative to energy methods. The method consists in a variable transformation that maps the high frequency response variable into an envelope variable characterized by a low wavenumber spectrum. In this paper it is shown that CEV still suffers of inaccuracies in its theoretical formulation. However, the results can provide at the present state of the work are comparable, probably better, with those obtained by other recent proposed procedures.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
