Abstract

An improved model of modal parameters of glass reinforced
plastic structures (GRP) is presented. The extensive analysis of
:he fitted experimental results proves that the quasi uniform mass
damping is the main feature of vibratory GRP structures.
Consistent with the analysis it is stated that the number of
boi~ndary degrees of freedom, code number, volume fraction and
typical order of natural mode have significant effects respectively
on controlling the type of each set of quasi rectangular hyperbolic
relations associated with the vibration damping of GRP
structures.
The close agreement between the numerical results of-' the finite
element model and the fitted experimental results shows the
efficiency and applicability of the present modelling techniques,
resulting in significant simplifications in solutions of
idiosyncratic composite systems with lowest residual errors.
