Material research: Progressive damage simulation

Objectives

  • Review the existing methods and techniques for the progressive damage simulations of structural materials for wind energy applications
  • Develop analytical and numerical tools for the prediction of strength and life of the following structural materials:
    • Fibre reinforced polymers
    • Structural adhesives

Project summary

The efficient structural design of the wind turbine blades requires, among others, development of predictive models for the life prediction, residual strength and failure probability of the structural materials. The aim of this project is to review the existing methods and techniques and to propose and develop analytical and numerical tools able to simulate the damage evolution in fibre reinforced polymers and structural adhesives subjected to multiaxial quasi-static and fatigue loadings.
