Investigation on the Design, Structural and Modal Analysis for Polymer Matrix Composites at 10º and 20º Twist

: 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

Important Announcements

All the authors, conference coordinators, conveners, and guest editors kindly check their articles' originality before submitting them to IJCERT. If any material is found to be duplicate submission or sent to other journals when the content is in the process with IJCERT, fabricated data, cut and paste (plagiarized), at any stage of processing of material, IJCERT is bound to take the following actions.
1. Rejection of the article.
2. The author will be blocked for future communication with IJCERT if duplicate articles are submitted.
3. A letter regarding this will be posted to the Principal/Director of the Institution where the study was conducted.
4. A List of blacklisted authors will be shared among the Chief Editors of other prestigious Journals
We have been screening articles for plagiarism with a world-renowned tool: Turnitin However, it is only rejected if found plagiarized. This more stern action is being taken because of the illegal behavior of a handful of authors who have been involved in ethical misconduct. The Screening and making a decision on such articles costs colossal time and resources for the journal. It directly delays the process of genuine materials.
