In this thesis results from the existing test machines that Fresenius Kabi AB, Uppsala, uses today have been compared with the complaints that the customers returns to the company. By this the differences between the damages and holes on the outer pouches of the bags could be found. Two different machines have been used: the shaking table and Gelbo Flex tester. The holes on the pouches were located by filling them with air and put them in water and look for bubbles. A microscope was used to find the reasons behind the wear. The dominating types of wear were creep, abrasive wear and fatigue wear and temperature increase makes the bag even more sensitive for any type of wear. A new type of equipment was built to be able to test the pouches on the shaking table without friction heat. These tests showed much better results that looked more like the complaints. To reduce the number of holes, new designs on the outer pouches were tested. A better design was found by using tables and PUGH-matrix, but some holes were still there. Therefore some calculations were made to get more realistic parameters so the tests got the same severity as a real transport. Some of the parameters were tested to find the ones that get results most similar to a real transport. The new design was then compared with the old one, to see if the difference was big enough to say that the new design is better even in this test. The results showed clearly that the new design was better

Detta examensarbete tar plats i Bredäng, söder om Stockholm. Projektet har varit en undersökning i hur man omarbetar, anpassar och informerar två befintliga bostadshus från miljonprogramsåren till dagens behov. Med syfte att skapa kontinuitet och komplexitet i dessa strikta strukturella fält, detta genom en formfinnande process där textilt skumgummi har använts som ett medlande objekt av additiv och subtraktiv information med referenser till “The Renewed Novelty of Symmetry” av Greg Lynn. Det är ett spekulativt projekt som tar upp frågor kring byggnaders evolution samt begreppet "mismatch", med ambitionen att dessa byggnader skall få fortsätta berättelsen om nya sätt att bygga bra bostäder för framtiden. Den berättelse som de en gång var en del utav när miljonprogrammet utvecklades, då avståndet mellan forskning och profession var mycket kort och byggnaderna byggdes tillsammans med de nyaste idéerna och teknikerna för den tiden. Men att låta livet i och runt dessa byggnadsstrukturer ha en inverkan på sin egen situation samt att förankra byggnaderna på platsen har varit fokus. / This thesis project has been an investigation in how to rework, adapt and inform two existing housing structures from the million-programme-era in Bredäng, south of Stockholm, to the needs of today. Aiming to create continuity and complexity in these structural fields through a form finding process using textile foam rubber as the intermediating object of additive and subtractive information, referring to “The Renewed Novelty of Symmetry” by Greg Lynn. It's a speculative project that takes on the question of building evolution and mismatch, where I want these buildings to continue the story of new innovative ways of building good housing for the future. The story which they once where part of when the million-program-era was developed, when the distance between research and profession was short and the buildings where built with the new building ideas and techniques of that time. So trying to let the life within and around these building structures have an impact on its own situation and also tying the buildings to the site has been the main focus.
