1. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form
University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Abstract : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. READ MORE

3. Modeling of a ball contact with a coated plate
University essay from KTH/Skolan för industriell teknik och management (ITM)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

4. Study of Corner and Bathtub Attachments with Respect to Static Sizing
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : This master thesis studied the possibilities of implementing new handbook methodologies for sizing of corner and bathtub attachments with respect to static strength. Parametric studies of corner and bathtub attachments were performed in order to examine the effect of boundary conditions and vital dimensions with respect to static strength. READ MORE

5. Development of a subject specific 3D knee finite element model to estimate the effect of weight loss on cartilage biomechanics
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : Osteoarthritis (OA) is a common musculoskeletal disorder that degrades articular cartilage and is a leading cause of disability worldwide. Overweight has been considered a major risk factor of knee OA, and it is known that weight loss may reduce the risk of knee OA. READ MORE
