Risk Quantified Structural Design and Evaluation

Abstract

The objective of this program is to demonstrate the benefits of a probabilistic design/risk assessment framework during all stages of aircraft structural design and evaluation. This objective is to be accomplished by performing a series of deterministic and probabilistic analyses for various levels of design refinement from conceptual design to preliminary design to detailed design. A benchmark problem of current interest to AFRL/VA has been selected to demonstrate the framework. This problem is a design application relating to the thermal buckling response of a representative exhaust-washed aft deck structure. In addition to using this benchmark problem to demonstrate the benefits of a probabilistic design/risk assessment framework, practical methods for reliability-based design of aerospace structures are investigated.
