1. 16. Virtual testing of self-piercing rivet connections

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Daniel Andersson; Fredrik Saliba; [2020]
   Keywords : FEM; SPR; self-piercing rivets; self piercing rivets; LS-dyna; Explicit FEM; lap-shear; cross-tension; KS2; r-adaptivity; 2D axisymmetric; axisymmetric;

   Abstract : The automotive industry is currently trying to replace the conventional steels to lightweight materials such as aluminum or carbon fiber to meet all stricter emission targets. When using such materials, traditional joining methods, such as spot welds, could be difficult to use. Therefore, more focus has been put on self-piercing rivets (SPR). READ MORE

3. 17. Dynamic Soil-Structure Interactionof Soil-Steel Composite Bridges : A Frequency Domain Approach Using PML Elements and Model Updating

   University essay from KTH/Bro- och stålbyggnad

   Author : DIEGO FERNANDEZ BARRERO; [2019]
   Keywords : Dynamics; soil-steel bridges; soil-structure interaction; model updating; PML; particle swarm; corrugated steel plates; frequency domain assurance criteria; parallel computing 2;

   Abstract : This master thesis covers the dynamic soil structure interaction of soil-steel culverts applyinga methodology based on the frequency domain response. At the first stage of this masterthesis, field tests were performed on one bridge using controlled excitation. READ MORE

4. 18. Analysis of the intake grill for marine jet propulsion

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

   Author : Marcus Söderberg Jansson; [2019]
   Keywords : Intake grill; Waterjet; Fluid Dynamics; Intagsgaller; Vattenjet; Strömning;

   Abstract : Marine waterjet propulsion is a technology that has been developed and refined since the early 1950’ and is proven highly useful for high speed applications with vessels in varying sizes. The intake grill is a component that is mounted in line with the hull to prevent debris from traveling through the waterjet. READ MORE

5. 19. Numerical ice sheet modelling using FEniCS

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : André Löfgren; [2019]
   Keywords : ;

   Abstract : The increase in computational power in the last 20 years has made it feasible to solve the full Stokes equation for ice flow, using finite element methods (FEM). However, the numerical properties of these equations remains largely unknown. This is due to their nonlinear nature, which makes them hard to analyze mathematically. READ MORE

6. 20. A Generative Design of TimberStructures According to Eurocode : Development of a Parametric Model in Grasshopper

   University essay from KTH/Bro- och stålbyggnad

   Author : NICOLINA ANDRÉN JAKOBSSON; SIMON BOHMAN; [2019]
   Keywords : Parametric design; Timber; Optimization; Generative Design; Glulam; Grasshopper; Python i;

   Abstract : The interest of timber structures has in recent years increased, primarily due tothe environmental benets of timber. This has created an increased demand forstructural engineers with timber expertise. At the same time the concept of structuralparametric design have become more popular. READ MORE
