Introduction
Laminated composite components used in many engineering applications are
predominantly exposed to stochastic dynamic loads. One of the most
important differences that filamentary composite laminates have over
traditional materials is their anisotropic behavior. Another important
feature is that the stress-strain relations exhibit significant
non-linearities even for modest loads, when the loading is not parallel
to the filaments or when the loading involves shear. The random response
of laminated composite plates modelled with finite elements, and
including non-linearity in the shear stress-strain law, is determined
using the method of equivalent linearization. This is an extension of
the formulation for the in-plane response of a single lamina developed
by Harichandran and Hawwari (1992). Kirchhoff plate theory is used here
as a starting point, and the use of a high-order shear theory is under
investigation.
