En jämförelse mellan austenitiska och rostfria stål
The austenitic stainless steel 316L has been compared to duplex stainless steels to be able to highlight a choice of material for manufacturing of spare tanks used for cooling water at nuclear power stations on the Swedish west coast. In this report 316L and the duplex stainless …
… was to change the material in the axis and the hub to a more high quality steel with a larger yield and tensile strength. By using a typical steel for turbine axis, with a yield strength of 700 MPa for the axis and 455 MPa for the hub, a safety factor of 2,8 was achieved. The …

… process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear …
… floor the support system has been strengthened with columns and beams of steel. A calculation shows that the newer members are no longer needed but they must have been in the 1930s, when the steel was added. Reinforcements could result in problems at the joints to the old …
Pelletspanna från kvänum energi
… price and environmental impact point of views. From design point of view, steel and aluminum are equivalent for the purpose, but in terms of cost, aluminum is more expensive. However the recycling option is significantly better for aluminum. EPS (Environmental Priority …
En jämförelse mellan Eurokod och BKR
… this thesis is to investigate the degree of influence of holes in the web of steel beams with long spanson weakening of their bearing capacity. Making holes in the web of the beam generally reduces the bearing capacity of the beam. However, it might be necessary seen from both …
trygg-bas script och möjligt sporttävlingsscript hos idrottsaktiva skolbarn och samband med föräldrainvolvering i barnets idrott
… & Apetroaia, 2011), samt blev intervjuade (Friends and Family Interview, FFI; Steele & Steele, 2005). Idrottsenkäter besvarades av barn och föräldrar. Idrottsaktiva skolbarn i åldern 9-12 år (N = 86) och föräldrar (N = 74) deltog. Nivåerna av föräldrapress är låga, dock något …
En enkätstudie
Stålindustrin förser såväl människor som samhället med många nödvändiga byggstenar. I Sverige finns tolv ståltillverkande anläggningar och hela 80 % av stålet exporteras. Som alla andra tillverkande industrier har den flera miljöaspekter att ta hänsyn till, men stålets nytta …
En jämförelse av byggnadstekniska metoder för sammanbindning av skalmurar
… are reconstructional masonry work using ”through-stones”, wall ties out of steel and supportive buttresses. These techniques are investigated regarding their constructive actions and suitability for The City wall of Visby. Masonry work using ”through-stones” consists of placing …
Investigation of bondning mechanisms at the pressing of metal laminates
… been to acquire a deeper understanding of what is happening in the bond for steel and for the factors that form the basis for a bond to develop between metals in the production of laminates by pressing. The merge has been done by pressing and the surfaces after the experiments …
Ett makro för Tekla Structures
… was to create a macro that would help EABAB automate the process of designing steel trusses. When run in Microsoft Excel, the macro imports and processes coordinates from a calculator program. The data is then imported into the Building Information Modelling software Tekla …
… internal materials handling. In this thesis the internal material handling of steel frames has been studied at a factory in Vaggeryd. The goal of this study is to investigate the problems that exist with the current production flow of products and provide suggestions on how it …
