1. 1. Modeling of a ball contact with a coated plate

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Mohammadreza Saeedi; [2023]
   Keywords : Pin on disc tribometer; coating; contact mechanics; finite element method; tribology; Pin on disc tribometer; beläggning; kontaktmekanik; finita elementmetod; tribologi;

   Abstract : During tightening of a screw, the variation in friction will affect the force acting on the joint, especially when tightening using torque as a control parameter. So, it is crucial to have a proper understanding of the contact mechanism and friction in the screw head to joint and thread interfaces. READ MORE

3. 2. 2D Modelling of Geosynthetically Reinforced Piled Embankments : Calibration Methods in PLAXIS 2D & Review of Analytical Guidelines

   University essay from KTH/Jord- och bergmekanik

   Author : Maya Sleiman; [2021]
   Keywords : ;

   Abstract : This thesis focuses on the 2D modelling of Geosyntheticaly Reinforced Piled Embankments (GRPE) in PLAXIS 2D. In doing so, it explores two main aspects: 1) the calibration of Interface Stiffness Factors (ISFs) governing the soil-pile interaction of Embedded BeamRow (EBR) elements in PLAXIS 2D, and 2) the prospects and limitations of modelling geogrids (GR) in PLAXIS 2D when underlain by EBR elements; although several studies have validates the EBR element in modelling piles, none address the geogrid-EBR interaction and its implications on modelling GRPE systems.

4. 3. Friction and wear study of lean powder metallurgy steel in a lubricated sliding contact

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Caroline Lejonklo; [2019]
   Keywords : Lean steel; Powder metallurgy PM ; Powder metallurgy steel PM steel ; Friction; Wear; Sliding contact; Lubricated; Porosity; Tribology; Adhesive wear; Abrasive wear; Gear; Gear tooth; Particles; Polyalphaolefin 8 PAO 8 ; Contact pressure; Density; Light optical microscopy LOM ; Scanning electron microscopy SEM ; Energy-dispersive X-ray spectroscopy EDS ; Vertical svanning interferometry VSI ; Pin on disc; Pin-on-disc;

   Abstract : A fairly new technology used to produce metallic components is powder metallurgy (PM). Among the advantages with this technique are decreased cost of production for complex-shaped parts, new alloys are made possible, reduced end processing, less material loss, and vibrational damping effects.

5. 4. Significance of Fracture Patterns in a Rock Mass during Excavation by Blasting in Bandhagen, Sweden

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Mattias Ryttberg; [2015]
   Keywords : Fracture sets; rock excavation; rock wall; instability; Spricksystem; utschaktning; bergvägg; instabilitet;

   Abstract : When excavating a rock wall by blasting, pre-existing structures in the rock has a strong impact on the stability of the wall. For excavation in Bandhagen in Stockholm, the nature and orientation of the pre-existing geological features, namely fractures, were not taken into consideration before excavation begun. READ MORE

6. 5. Simulating propeller and Propeller-Hull Interaction in OpenFOAM

   University essay from KTH/Marina system

   Author : Reza Mehdipour; [2014]
   Keywords : CFD; OpenFOAM; AMI; MRF; Open Water Characteristics; Self-Propelled Ship; Scalability; Parallel Computing;

   Abstract : This is a master’s thesis performed at the Department of Shipping and Marine Technology research group in Hydrodynamics at Chalmers University of Technology and is written for the Center for Naval Architecture at the Royal Institute of Technology, KTH.In order to meet increased requirements on efficient ship propulsions with low noise level, it is important to consider the complete system with both the hull and the propeller in the simulation.
