Nonlinear Response and Fatigue of Surface Panels by the Time Domain Monte Carlo Approach

Abstract

The objective of this Phase I research is to develop a computational procedure for predicting the life and reliability of metal and composite structural panels subjected to complex dynamic loads from acoustic, aerodynamic, and thermal environments. The proposed research uses a time domain Monte Carlo method to develop analytical equations of high accuracy and efficiency. The time domain Monte Carlo method will permit an examination of the effects of peak stresses and exceedances; subsequently, meaningful predictions of structural life (fatigue) can be made. Phase I research will be used to verify the Monte Carlo time domain analysis. The resulting computational procedure will be used to establish the feasibility of developing either a discretized (finite element) or numerical computer program to be completed during any Phase II effort. This research will lead to a new technology base for estimating the nonlinear response characteristics of a new generation of aircraft exposed to severe acoustic, aerodynamic, and thermal environments.
