1. 1. Method Development & Analysis of Seals using FEM

   University essay from KTH/Maskinkonstruktion

   Author : Lovisa Svanborg Östlin; [2023]
   Keywords : FEM; guidelines; hyperelastic materials; hyperelastic material models; method development; seals; FEM; riktlinjer; hyperelastiska material; hyperelastiska materialmodeller; metodutveckling; tätningar;

   Abstract : Hyperelasticity is a significant property of rubber, taken advantage of in engineering applications. A common application is the use of seals to prevent fluid transfer (liquid or gas) between solid regions. Volvo CE is often depending on external supplier when developing seals. READ MORE

3. 2. Material Characterization and Blade Impact Simulation

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

   Author : Gustaf Bodare; [2022]
   Keywords : Strain rate dependency; Split-Hopkinson pressure bar; Digital image correlation; LS-DYNA; FEM; SPG;

   Abstract : Blades used on brushcutters and lawn mowers are subjected to a wide variety of working conditions. Besides continuous loads from cutting grass, the blades are also subjected to accidental impacts of branches, stones and structures. READ MORE

4. 3. Finite Element Analysis of Stresses in the MIST CubeSat due to Dynamic Loads During Launch

   University essay from KTH/Lättkonstruktioner

   Author : Carl Järmyr Eriksson; [2021]
   Keywords : Satellite; CubeSat; Nanosatellite; Dynamic Loads; Launch Loads; Finite Element Analysis; FEA; Quasi-static Acceleration; Modal Analysis; Random Vibration; Shock Loads; satellit; CubeSat; nanosatellit; dynamiska laster; uppskjutningslaster; finita elementmetoden; FEM; kvasistatisk acceleration; modalanalys; stokastiska vibrationer; chocklaster;

   Abstract : A finite element model of the CubeSat MIST was created, in order to assess the stresses that occur in the satellite in response to loads during its launch. Due to size limits of thesoftware used, simplifications had to be made to the geometry of the model. READ MORE

5. 4. The effect of printing parameters on the deformation and microstructure of Inconel 718 : A study in pulsed laser and powder based directed energy deposition additive manufacturing

   University essay from KTH/Materialvetenskap

   Author : Elias Repper; [2020]
   Keywords : Laser; Additive Manufacturing; Metal; Deposition; Quasi-continuous-wave; Pulsed; Ni-base superalloy; Laves; Deformation; Residual stresses;

   Abstract : Additive manufacturing has the power to redefine how we create components. In order to minimize removal of printed material, deformation must be kept a minimum. When deposition rate is increased during directed energy deposition so is the power requirement for melting the feedstock. READ MORE

6. 5. Cross-comparison of Non-Linear Seismic Assessment Methods for Unreinforced Masonry Structures in Groningen

   University essay from KTH/Betongbyggnad

   Author : Viktor Peterson; Zihao Wang; [2020]
   Keywords : Non-linear time-history analysis; non-linear pushover analysis; N2-method; equivalent frame model; continuum model; numerical seismic assessment; unreinforced masonry buildings; Olinjär tids-historikanalys; olinjär stjälpningsanalys; N2-metoden; ekvivalent rammodell; kontinuumelement modell; numerisk jordbävningsanalys; oarmerade murverksbyggnader;

   Abstract : A large amount of low-rise unreinforced masonry structures (URM) can be found in Groningen, the Netherlands. More and more induced earthquakes with short duration have been detected in this region due to gas exploitation. READ MORE
