Wear Model for Wind Turbine Blade

[smartchin77]

I am working on a water droplet erosion model for a wind turbine blade. When a water drop hits the wind turbine blade, it generates Rayleigh waves and induces stress in the blade.
How can I correlate this impact stress with the eroded volume of the material?

Data available:

[li]Rainfall parameters like droplet size, velocity, rainfall flux[/li]

Droplet impingement produces the same type material loss as cavitation ; Both are impact by small drops, rough irregular pitting ( at least in steel). I doubt Rayleigh waves are a factor unless fatigue cracks were produced by cyclic stresses.
