Fatigue Life of Composite Structures in Extreme Environments
Abstract
Prediction of the dynamic response and the fatigue life of structures, i.e. panels, subjected to both high temperatures/ thermal gradients and high level acoustic excitations. The determination of reliable approximations of the statistics of the panel response to the random acoustic excitation will be accomplished by relying on two separate equivalent linearization strategies. The first method uses a Gaussian process. The second method relies on a mean equal to the buckled states and the panel response is obtained as the sum of zero mean fluctuations around these positions.
