Although several theoretical investigations have been carried out on the non-stationary parametric response of structures, experimental evidence is far from adequate in many cases and is even non-existent in some cases. In this context, an experimental study of the non-stationary parametric response of simply-supported non-linear rectangular plates was performed. Special attention was paid to satisfy the boundary conditions assumed in the analytical model so as to draw conclusions with sufficient degree of confidence. Experimental data have been compared with analytical predictions to form a qualtitative and quantitative verification of the solution.
