Abstract
This paper reviews recent research into the development of simple relationships between mean-square dynamic strain and vibrational velocity for the estimation of maximum dynamic strain levels in randomly vibrating structures. These relationships provide a consistent approach with a firm theoretical basis for the estimation of dynamic strain from vibrational velocity in all types of structures, independent of the type of structural element (beam, plate or cylindrical shell) and the frequencies of excitation (resonant, non-resonant, multi-modal or broad-band vibration in the low-, mid- and high-frequency ranges). The relationships developed are based on farfield relationships, factors for the effects of evanescent waves, and correlations between the spatial maxima of dynamic strain and velocity.
