Abstract: Filamentary composite structural components used in engineering applications are usually subjected to stochastic loads. Composites have strongly anisotropic properties and display significantly nonlinear behavior when loaded in shear. The finite element technique is used together with the method of equivalent linearization to study the in-plane non-linear random vibration response of uni-directional laminae. The method may be easily adapted to analyze laminated composites.
