Wind Turbine Blade Stress Analysis
Code inputs are the following, these are required by the researcher to calculate before hand:
1- Weight of Turbine blade.
2- Average acting aerodynamic force on the blade.
3- Modulus of Elasticity for used material.
4- Area of moment for Turbine cross section.
5- Turbine Length.

5- Turbine Length.
Remember an increase in blade weight would increase its strength but would also be lethal and would cause unwanted vibrations during transient flows. A ready code for blade analysis.
