1. 1. Characterization of Fiber Orientation and Weld Line Effects in Reinforced Plastics with Reduced CO2eq Emissions

   University essay from Jönköping University/JTH, Material och tillverkning

   Author : Anders Tolf; Markus Johannesson; [2022]
   Keywords : Fiber-reinforced plastics; GFRP; Reduced carbon dioxide equivalent materials; Experimental; Uniaxial tensile test; Uniform fiber orientation plate; Tensile strength; Fiber orientation; Weld line; Fracture analysis; Microscopy;

   Abstract : With increasing emphasis and regulations on the environmental footprint in industries, the integration of reduced carbon dioxide equivalent (CO2eq) plastic materials is desirable. Fiber-reinforced plastic materials mechanical properties differ with varying fiber orientations. READ MORE

3. 2. Laser-arc hybrid welding of high strength steel : Weld quality and process stability

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : David Lohse; [2021]
   Keywords : Laser; arc; hybrid; welding; high; strength; steel; high-strength; HSLA; weld quality; process stability;

   Abstract : The development of high strength steel enables constructions to be made with less material than with previous used steel grades. The possibility of creating lightweight constructions with the same or even better mechanical properties is of high focus in the steel industry today. READ MORE

4. 3. FE-model for prediction of welding distortions in components made of preformed stainless steel sheets

   University essay from KTH/Hållfasthetslära

   Author : Tom Glansholm; [2020]
   Keywords : Welding simulation; distortions; Ferritic stainless steel; EN1.4509; FEM; Solid mechanics; Residual stresses; Svetssimulering; deformationer; restspänningar; Ferritiskt rostfritt stål; EN1.4509; Finita elementmetoden; Hållfasthetslära;

   Abstract : This master thesis was carried out at Scania CV AB. The focus for this thesis is the prediction of welding distortions that can cause problems in the manufacturing process of Scania's after-treatment system. The after-treatment system is mainly assembled by sheet metal plates of the ferritic stainless steel EN 1.4509. READ MORE

5. 4. Numerical Assessment of Defects Effect on Boltless Composites Longitudinal Joints

   University essay from KTH/Lättkonstruktioner

   Author : Mara Santaniello; [2020]
   Keywords : ;

   Abstract : The work presented in this thesis focuses on the numerical assessment of defects effect on potential boltless design for fuselage panels longitudinal joints, typically identified as High Load Transfer (HLT) configuration. Nowadays, the state-of-art joining technique for primary aircraft composite structures, such as fuselage barrels, is still mechanical fastening. READ MORE

6. 5. Thermo-Mechanical Fatigue Assessment of Marine Boiler : Using linear Finite Element Analyses

   University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Author : Adefemi Samuel Alagbada; [2020]
   Keywords : Marine Boiler; FEA; Thermo-mechanical Loading; LEFM; Paris law; Flaws; RAO.;

   Abstract : This thesis is on fatigue crack growth assessments of a thermomechanical loaded Marine Boiler- Sunrod CPDB12. The installation position of the marine boiler in the ship in relation to its fatigue life under mode 1 loading is investigated. READ MORE
