Flow-induced vibration of hydrofoils affects pressure pulsations on their surfaces and influences cavitation inception and desinence. As these pulsations depend on the hydrofoil material, cavitation inception and desinence numbers for hydrofoils of the same shape made from different metals can be substantially different. This conclusion is based on the comparison of the multistep numerical analysis of fluid–structure interaction for hydrofoils Cav2003 with earlier obtained experimental data for them. The material impact on cavitation must be taken into account in future experiments.
