Acoustic Fatigue Crack Growth Prediction in Coupled Air Structures

Abstract:

In this paper, crack growth of thin-walled cylinders containing an initial crack under acoustic plane wave is analyzed. A coupled air-structure modeling is considered for the analyses. For this purpose, a methodology for computational modeling of the fatigue crack growth in cracked cylinders using finite element method is presented. Effects of various parameters such as crack length increment and boundary conditions on the crack growth rate are investigated.
