1. 1. FE-modelling of glulam connection in a pre-tensioned glulam truss : Detailed Finite element modelling of the connection between primary beam and compression stud in a sub-tensioned glulam roof truss

   University essay from KTH/Bro- och stålbyggnad

   Author : Edward Sebastian Swaretz; [2022]
   Keywords : Glulam; sub-tensioned roof truss; connection; instability; Abaqus Standard; Finite element method;

   Abstract : After the collapse of the roof structure in Tarfalahallen 2020, great attention has been focused on instability of sub-tensioned glulam roof trusses. Investigations were launched to find the reason for the collapse and the cause was instability in the roof truss that supported the roof. READ MORE

3. 2. FE Simulation of protective insulation of catalysts in exhaust after-treatment systems of trucks and buses : Investigation and characterization of catalytic converter support mat material for accurate modeling in finite element simulations

   University essay from

   Author : Manroop Bhattasali; [2022]
   Keywords : Catalytic converter; packaging mats; support mats; compression; friction; hyperelastic; hyperfoam; viscoelastic; canning; finite element;

   Abstract : The increase of new and ever more stringent emission legislation has brought about with it a surge in the demand for more sustainable automotive solutions. This has particularly been the case for automobiles, including heavy-duty vehicles like trucks and buses, with internal combustion engines, which now require the design and manufacturing of more durable and reliable components.

4. 3. Monitoring and Modelling of the Abiskojåkka Bridge

   University essay from Luleå tekniska universitet/Byggkonstruktion och brand

   Author : Kasper Furenstam; [2020]
   Keywords : Prestressed bridge; Abisko; Monitoring; thermal effects; FEM;

   Abstract : The infrastructure of today is getting older and problems caused by deterioration over time is affecting the service life of these structures. In Sweden most of the existing bridges were constructed 60 to 70 years ago, rising the need to determine the state of health of the bridges as the maintenance costs will increase heavily. READ MORE

5. 4. Behavior prediction of concrete dams

   University essay from KTH/Betongbyggnad

   Author : Isak Nilsson; Leonard Sandström; [2020]
   Keywords : Concrete dams; dam monitoring; dam safety; measurement evaluation; databased models i;

   Abstract : As many dams were built around 1950, the expected life span of these dams are about tobe reached. With this, the need for monitoring and increased understanding of the damsstructural integrity increases. In order to prevent failures, two warning signals are defined;alert and alarm. READ MORE

6. 5. EXPERIMENTAL CHARACTERIZATION AND COMPUTATIONAL DYNAMIC MODELLING OF A VIOLIN Analysing the effects of creep and string tension

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Joel Värelä; Erik Tunlid; [2020]
   Keywords : Violin; experimental modal analysis; modal analysis; EMA; finite element method; FEM; FE; wood; Technology and Engineering;

   Abstract : During the 17th and early 18th century Antonio Stradivari built around 900 violins, that still today are considered some of the best instruments ever created. The theories of how it was possible for a luthier active 300 years ago to create instruments of this quality are many, including unique wood properties and secret building techniques. READ MORE
