1. 1. Evaluation of Crack Depth Meter - An investigation of the crack depth meters possibilities and limitations for commonly occurring damage mechanisms

   University essay from KTH/Hållfasthetslära

   Author : Alfred Norberg; [2023]
   Keywords : Crack depth measurement; RMG 4015; ACPD; Damage Mechanism; Evaluation; FEM Simulation; Sprickdjupsmätning; RMG 4015; ACPD; Skademekanism; Utvärdering; FEM-simulering;

   Abstract : In this master thesis, the accuracy of the crack depth meter RMG 4015 was evaluated for different types of cracks with various damage mechanisms. In total, 61 crack depth measurements were conducted with the crack depth meter on 56 cracks which were located in the 23 different test pieces supplied by Kiwa. READ MORE

3. 2. Evaluation of Coefficient of Friction in Oblique Helmet Impacts: An Experimental and Numerical Study

   University essay from KTH/Hållfasthetslära

   Author : Philip Singh; [2022]
   Keywords : FE model; friction; helmet impact; LS-DYNA; FE-modell; friktion; hjälmislag; LS-DYNA;

   Abstract : The focus of this thesis was to increase the knowledge in the area of "dynamic friction" during oblique helmet impacts, both experimentally and numerically. Physical experiments have been performed with multiple helmets, different angles of the anvil and different surface materials, with results of impact forces from the anvil and accelerations of the head.

4. 3. Linear Impact of Bicycle Helmet – Experimental Testing and FE-modelling

   University essay from KTH/Hållfasthetslära

   Author : Ludvig Dahlin; Ebba Larsson Regnström; [2022]
   Keywords : FEM; Finite element method; bicycle helmet; impact modelling; solid mechanics; FEM; Finita element-metoden; cykelhjälm; islagsmodellering; hållfasthetslära;

   Abstract : The aim with this master thesis was to set up a FE-simulation of an impact test of a bike helmet in LS-DYNA that correlates well with the peak acceleration score of a real life impact test. Furthermore, a parametric study has been performed in LS DYNA to investigate the robustness of the model, as well as to see which parameters have a great influence on the peak acceleration score.

5. 4. Operational modal analysis and finite element modeling of a low-rise timber building

   University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

   Author : Viktor Petersson; Andreas Svanberg; [2021]
   Keywords : Timber structure; Dynamic behavior; Operational modal analysis; FE-modeling; Mode shape; Natural frequency.; Träbyggnad; Dynamiskt beteende; Operational modal analysis; FE-modellering; Egenmod; Egenfrekvens.;

   Abstract : Timber is a building material that is becoming more common and of interest for use in high-rise buildings. One of the reasons is that timber requires less energy input for the manufacturing process of the material compared to non-wood based materials. READ MORE

6. 5. 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
