N2 - A simple dynamic model of a general buckled plate using a single mode model is used to present the typical trend of nonlinear behavior. The nonlinear dynamic buckling of curved plate acted upon by a sinusoidal excitation and its effects on the overall dynamic response can be easily interpreted using the single-mode formula. The important non-linear dynamic characteristics of curved plates are found to be the transition from softening spring effects to hardening spring effects through the intermediate region of chaotic motion. The chaotic motion is an intermittent motion with large amplitude between the two static buckled positions of the plate. The theoretical predictions are in agreement with the experimental results. The experience from the studies can also be used to improve the testing and monitoring techniques for noise transmission and nonlinear vibration of curved plate under acoustic or airflow load.
