Finite element discretisations of higher order, applied to unsteady equations, generate nodal equations of unequal form. The stability analysis of a time-discretisation scheme for this system, by the local modal approach, therefore cannot be used. In this paper it is shown how, at the expense of a l

The use of scanning laser Doppler vibrometry (SLDV) o!ers many opportunities to increase the investigation capability of experimental vibration testing. Nevertheless, its employment introduces a number of new problems with respect to traditional measurement techniques. In this work, after a brief i

This paper presents two efficient modal approaches as an alternative to direct formulations for the time-harmonic dynamic analysis of structures with random material and shape parameters. In both approaches, the structural eigenproblem is solved and complemented by a sensitivity analysis to the rand

A new analytical method is proposed for the estimation of eigensolutions for undamped and proportionally damped discrete vibratory systems when the system parameters are uncertain or random variables. Given several simplifying assumptions, a direct product technique is used to estimate the first and
