I am pleased to invite you to watch my presentation that I held at the 5th Wind & Drivetrain Conference on April 7, 2022.
My Name is Lars Pilgaard MIKKELSEN, and I work at the Technical University of Denmark (DTU). For the last 10 years, I have been an Associate Professor in the Department of Wind Energy at the Technical University of Denmark. My work includes both teaching and research in the field of wind turbine blade materials. My focus is on linking experimental observations with numerical predictions on the material scale which lately has been concentrated around mapping x-ray tomography-based microstructures into finite element models.
Abstract:
Large wind turbine blades rely on composite materials with excellent and predictable material performance. This presentation demonstrates different cases for modeling composites aimed at the wind turbine blade application. The demonstration will be given using the commercial finite element code Abaqus. The demonstration will cover the ability to model the actual fiber, bundle, and fabric architecture as well as the matrix material performance of specific composite samples. It will be demonstrated how a precise numerical representation of a full cross-section of a material test sample containing 100.000’s fibers is translated from full 3D x-ray CT scans to high fidelity finite element models. Some of this work includes a Fortran-based implementation of user-defined user-element and user-materials, as well as material orientation mapping.
