1. 11. Modernized 6 and 10-ton Dock Levelers

   University essay from Lunds universitet/Innovation

   Author : Viola Nilsson; Rebecka Karlsson; [2021]
   Keywords : Dock leveler; FEM; stress; sheet metal; load case; Technology and Engineering;

   Abstract : This Master Thesis is made in collaboration with ASSA ABLOY Entrance Systems and addresses the issues and problem areas of two dock leveler models; 60 kN and 100 kN to find a new improved design. After the following product development process, a new concept was created which could withstand applied forces exceedingly. READ MORE

3. 12. 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

4. 13. Modelling of Laser Welding of Aluminium using COMSOL Multiphysics

   University essay from KTH/Materialvetenskap

   Author : Jie Chen; [2020]
   Keywords : laser welding process; aluminium alloy; thermal-mechanical; COMSOL Multiphysics; hot cracking; thermal model; CFD model; mechanical model; Marangoni effect; lasersvetsningsprocess; aluminiumlegeringar; termisk-mekanisk; COMSOL-flerfysik; hetsprickning; termisk modell; CFD-modell; mekanisk modell; Marangoni-effekt;

   Abstract : This thesis presents a modelling approach of laser welding process of aluminium alloy from the thermo-mechanical point of view to evaluate the occurrence of hot cracking based on simulation results and relevant criteria. The model was created stepwise in COMSOL Multiphysics, starting with the thermal model where heat conduction of solid and liquid phase was computed. READ MORE

5. 14. Mechanical modelling of gaskets in exhaust after-treatment system of trucks

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Aneesh Ravikumar; [2020]
   Keywords : ;

   Abstract : With the world proceeding towards a clean and sustainable environment,the creation of technology and its implementation also needs to be sustain-able. The importance of combustion engine vehicles to meet more stringentemission standards puts a requirement on the industry to develop suitableafter-treatment systems to meet those standards. READ MORE

6. 15. Assessment of creep damage in Fe-Ni-Cr alloys

   University essay from KTH/Hållfasthetslära (Avd.)

   Author : Frans Sorsh; [2019]
   Keywords : ;

   Abstract : It is only a matter of time before components working in high temperature environments fail due to creep. Design for creep is therefore of vital importance to maximize the lifetime of components and reduce costs that may arise from maintenance and replacement of components. READ MORE
