Crack Growth in Compressive Stress Fields
(Polytechnic University of Puerto Rico, 2013)
To understand how to analyze
Damage Tolerance in an aerospace component
loaded in compression one must first obtain correct
Fatigue Crack Growth curves. Once the fatigue
data curves are correct one could then move
forward ...
Analysis of Airfoils Modifications on Horizontal Axis Wind Turbine Blades
(Polytechnic University of Puerto Rico, 2020)
This project investigates the
combination of upper surface dimples and trailing
edge serrations of a 3D thin airfoil and their effect
on aerodynamic performance. Dimples are known to
reduce a golf ball’s drag while a ...
