Summary
This paper describes a numerical model and its finite element implementation that is
used to compute the cavitation effects in nonlinear acoustic fluid and the adjacent
flexible structure interaction. The system is composed of two sub-systems, namely,
the fluid and the flexible flat plate. A fully coupled approach using an iterative
implicit partitioned scheme was implemented in the work reported in this paper
which can account for the effects associated with a mutual interaction. A novel
implementation of acoustic cavitation was made possible with the introduction of a
simplified one-fluid cavitation model. The results obtained show that impact forces
caused by the impinging shock wave and reloading by the cavitation region collapse
have a considerable effect on the dynamic response of the flexible plate.
