Over the last years, UGent-MMS has developed the stand-alone BladeMesher software for generating finite element models of large wind turbine blades. The software reads in the material data and airfoil data of the wind turbine blade, and automatically constructs the geometry and finite element mesh for the blade. In a next step, the nodal and element information of the finite element mesh is written out to an input file for a commercial finite element solver (Abaqus in this case). As such, all features of a state-of-the-art finite element solver can be used to simulate the mechanical behaviour of the composite blade.
The concept of the BladeMesher software is described in the journal paper "Peeters, M., Santo, G., Degroote, J. and Van Paepegem, W. (2018). High-fidelity finite element models of composite wind turbine blades with shell and solid elements. Composite Structures, 200, 521-531" (https://doi.org/10.1016/j.compstruct.2018.05.091
The BladeMesher software is programmed in the Python language and counts more than 30,000 lines of code.
In this project, the BladeMesher software is further developed to include additional features for detailed modelling of adhesive joints (with cohesive elements). Further the computational mechanics of thick adhesive joints will be studied by finite element modelling. The properties of the bulk adhesive and interaction with the composite substrates will be included in the FEM models.
The project is funded by FWO-Vlaanderen and is a collaboration between Ghent University, Free University of Brussels (VUB) and EPFL (Lausanne, Switzerland). The researcher at Ghent University will be closely collaborating with two other PhD students at VUB and EPFL.
The research study at Ghent University is purely numerical, while the experimental work will be done at the two other universities.
Only candidates with a Master degree should apply. The candidate should have a strong interest in software development and finite element modelling. The candidate should have strong programming skills and computational mechanics background.
