PhD defence by Peter Riddersholm Lauridsen
Peter will defend his PhD thesis "A Contribution of Methods for Analysis of Laminated Composites and Adhesive Joints". Defence is in hybrid format.
06.07.2021 kl. 13.00 - 17.00
This PhD project has focused on structural testing and computational methods for fracture and fatigue problems in laminated composites and adhesive joints. Laminated composites and adhesive joints are extensively used in structures such as wind turbine blades, and the performance of these are pushed to the failure limits in order to obtain stiffer, stronger and lighter blades. These new methods will expand the possibilities in testing and designing modern wind turbine blades, and still ensure structural integrity.
First contribution is an unseen test fixture and method (TP-MMB), which is used for determination of mode mixity fracture resistance in laminated composites and adhesive joints. Second part is a contribution of three Finite Element based approaches for determination of so called Brazier forces or contributing forces, which is a second order effect also referred to as geometric non-linearity.
The aforementioned contributions are designed for analysis of laminated composites and adhesive joints. It can be concluded that both contributions are suitable for the wind turbine industry.
