: Finite element evaluation of large (over 0.5MW) nominal power Horizontal Axis Wind Turbine (HAWT) is performed
using ANSYS in this project. The strategy is based on the combination of an aerodynamic module, which provides the three
dimensional pressure distribution on the blades as input data in order to compute both, blade deformation and stress intensity
over the blades.This project also determines the natural frequency of the blade using modal analysis. The material used here
are polymer-matrix composites, they are Glass/epoxy, Kevlar/epoxy, Carbon/epoxy and E-glass/epoxy. The stress intensity and
displacement for different materials are compared and the best is highlighted which increases the life of the blade. This
provides future scope for alternative materials for wind turbine blade

We have kept IJCERT is a free peer-reviewed scientific journal to endorse conservation. We have not put up a paywall to readers, and we do not charge for publishing. But running a monthly journal costs is a lot. While we do have some associates, we still need support to keep the journal flourishing. If our readers help fund it, our future will be more secure.
