Abstract: The Finite Element Analysis (FEA) of marine propeller blade stress distribution due to hydrodynamic loading is presented and discussed. The analysis provided a better insight to complex marine propeller shape and interaction with hydrodynamic loadings. Stainless steel Wageningen B Series 3 blade propeller with 250 mm diameter, EAR of 0.5 and P/D ratio of 1.2 was adopted in the analysis. The propeller was subjected to the rotational speed of 0-6000 rpm. The pressure distribution demonstrated a positive pressure region on the face section and a negative region on the back section that produces the thrust generation. At 6000 rpm, a maximum positive pressure was achieved at 3225 kPa with a negative pressure of 7229 kPa. The hydrodynamic loading from the pressure distribution computation was applied to the stress distribution computation. From the analysis, the propeller blade stress distribution predicted a highly concentrated region near to the hub and decreasing with the growing value of the propeller radius. The highest stress value of 739 MPa at 6000 rpm was obtained at higher than the stainless steel yield stress (170 MPa) and the blade tip deflected towards the ship hull by 2.73 mm.
