[Objectives] The reliability of propeller stress has a great influence on the safe navigation of a ship. To predict propeller stress quickly and accurately. [Methods] a new numerical prediction model is developed by coupling the Boundary Element Method(BEM)with the Finite Element Method (FEM). The low order BEM is used to calculate the hydrodynamic load on the blades. https://www.nacrack.com/deal-alert-Dea-Eyewear-Jemma-deal-zone/
