A Reliability Based Design Method Evaluation for a Coupled Fluid-Structure System

This paper proposes a reliability based designing method study for a coupled fluid-structure system. The main objective is to achieve 90% confidance in our estimate of the failure probability. A First Order Reliability Method (FORM) analysis is performed for a double acoustic cavities numerical example. The evaluation of the (FORM) method is established through a reference Monte Carlo Analysis. The results show that the (FORM) method can approximate the confidence goal with a low computation cost.
