  1. 16. Non-Linear FE-Analysis of a Composite Action Girder with Coiled Spring Pins as Shear Connectors

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Simon Stahlin; [2019]
    Keywords : composite bridge; composite action; shear connector; coiled spring pins; finite element modeling; samverkansbro; samverkan; skjuvförbindare; spiralbult; finita element modellering;

    Abstract : For bridges to cope with increased requirements such as increased loads, strengthening work can be carried out. In cases where older steel-concrete bridges do not have a composite action, an alternative is to create composite-action to achieve a higher flexural strength. It is introduced by post-installing shear connectors. READ MORE

  3. 17. A Study of Vascular Plaque in the Carotid

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Victor Thun; Kristin Salmi; [2018]
    Keywords : ;

    Abstract : In 2015, cardiovascular diseases caused the death of 17.7 million people - 31 % of all deaths globally - making it deadlier than any other cause.Cardiovascular diseases often result from Arteriosclerosis, a disease where plaque builds up and clogs arteries. READ MORE

  4. 18. Finite element analysis of e-commerce cushioning in corrugated board

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : Dominykas Gudavicius; [2018]
    Keywords : ;

    Abstract : Corrugated board and other paper products are widely used in product packaging due to good mechanical properties, recyclability, price etc. Due to the growing e–commerce industry the dynamical behaviour of corrugated board is of particular interest. Paper exhibits an orthotropic behaviour and is a non–linear material. READ MORE

  5. 19. Optimal Control of Heat Transfer Rates in Turbochargers

    University essay from Linköpings universitet/Fordonssystem

    Author : Max Johansson; [2018]
    Keywords : Optimal control; Turbochargers; Heat transfer; Direct collocation; Gas stand;

    Abstract : The turbocharger is an important component of competitive environmentally friendly vehicles. Mathematical models are needed for controlling turbochargers in modern vehicles. READ MORE

  6. 20. Simulation of fatigue crack growth in coated cemented carbide milling inserts

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : André Tengstrand; [2017]
    Keywords : ;

    Abstract : The aim of this work is to create a nite element model that simulates fatigue crack growth in coated cemented carbide milling inserts. A typical fatigue wear of coated milling tools are comb crack formation on the cutting edges of the tool inserts. Comb cracks initiate from pre-existent cooling cracks in the coating layers. READ MORE
