  1. 21. 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. 22. QUALITY IMPROVEMENT OF CERAMIC PARTS FORMEDICAL APPLICATIONS THROUGHOPTIMIZATION OF THE ADDITIVE MANUFACTURING ANDPOST-PROCESSING PROCESSES

    University essay from KTH/Industriell produktion

    Author : Eva Hofacker; [2018]
    Keywords : ;

    Abstract : Additive Manufacturing (AM) is beneficial for medical applications in which tissues must be replaced because AM enables the fabrication of highly complex three-dimensional structures. In this study the AM and the post-processing steps of additive manufactured ceramic parts of a specific material for tissue replacement were examined in order to optimize the parts’ quality.

  4. 23. Development of UHPC concrete using mostly locally available raw materials

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

    Author : Lennart Nilsson; [2018]
    Keywords : UHPC; Ultra High-Performance Concrete;

    Abstract : The concrete technology has during the last century changed dramatically where the concept of high strength concrete has gone from 30MPa to well over 100MPa. UHPC has many areas of application and is used more and more frequently in all manner of structures. READ MORE

  5. 24. Finite Element Modelling and Parametric Studies of Semi-Closed Thin-Walled Steel Polygonal Columns - Application on Steel Lattice Towers for Wind Turbines

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

    Author : Bona Ryan; [2017]
    Keywords : Lattice tower; Thin-walled element; Semi-closed polygonal section; Finite element analysis; Parametric study; Buckling; Python script; Matlab script; Eurocode 3; Factorial design;

    Abstract : The trend of structural engineering in the recent years is toward the use of lighter and moreeconomical structural elements. In steel construction, peculiarly, thin-walled structural elements arebecoming more popular and have a growing importance. READ MORE

  6. 25. Investigation of the mechanical performance of metal-composite joints

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

    Author : Marc Olavide Rubio; [2017]
    Keywords : carbon fiber epoxy; AlSi-coated boron steel; metal-composite joints; double-cantilever beam test; end-notched flexural test; tensile test;

    Abstract : Composite materials are gaining the attention of several industries due to the high stiffness-to-weight and strength-to-weight ratios they offer. Especially in the automotive industry, demands on reduction of CO2 emissions is the major driving force towards lighter vehicles. READ MORE
