   Keywords : Welded joints; Fatigue; Pre-fatigue; Life extension; Fracture mechanics; Finite element analysis; HFMI; ; Svetsade fogar; utmattning; förutmattning; livsförlängning; frakturmekanik; finit elementanalys; HFMI; ;

   Abstract : High-Frequency Mechanical Impacts (HFMI) is a surface treatment technique utilized to introduce residual stresses and extend the service life of structures. This project primarily focuses on studying the life extension effects of HFMI on welded structures that have undergone fatigue and have existing cracks. READ MORE

6. 5. Weight Optimization of Vertical-Axis Wind Turbine Blades constructed in Swedish Fossil Free Steel : With respect to fatigue life time

   University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Author : Johannes Hall; Albin Larsson; [2023]
   Keywords : VAWT; Wind Turbine Blade; SSAB; Fossil-Free; Weight Optimization; Topology Optimization; Sizing Optimization; NACA 0018; STRENX 1300; Abaqus; Tosca Structure; VAWT; Vindturbinblad; SSAB; Fossilfritt; Viktoptimering; Topologioptimering; Size-Optimering; NACA 0018; STRENX 1300; Abaqus; Tosca Structure;

   Abstract : Wind turbines have been utilized for centuries to harness energy from the wind. Commercial wind turbine blades are typically made from composite materials, which are difficult to recycle, leading to blades ending up in landfills at the end of their lifecycle. Additionally, these materials contribute to microplastic pollution. READ MORE
