  1. 1. Tensile fracture of ice test methods and fracture mechanics analysis

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Lars Stehn; Luleå tekniska universitet.; [1993]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : This thesis is concerned with several aspects of fracture of both brackish (low salinity) sea ice and freshwater ice. The tests and analyses are confined to tensile, or in fracture mechanics language, Mode I, fracture. READ MORE

    Abstract : Wood is a complex material and the mechanical properties are influencedby a number of structural parameters. The objective of this study has been toinvestigate the relationship between the structure and the mechanical propertiesof hardwood. Two levels were of special interest, viz. READ MORE

  3. 3. Microstructure and mechanical properties of Ti-6Al-2Sn-4Zr-2Mo and Ti-6Al-4V influence of H, O and B

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Raghuveer Gaddam; Luleå tekniska universitet.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titanium alloys; Hydrogen; Oxygen; Boron; Tensile; Compression; Fatigue; Metallography; Fractography; Materials science - Construction materials; Teknisk materialvetenskap - Konstruktionsmaterial; Engineering Materials; Materialteknik;

    Abstract : Titanium and its alloys are used in a wide range of applications from aerospace, marine, biomedical implants and consumer goods, due to their superior specific strength, excellent corrosion resistance, and biocompatibility. In aerospace applications, these alloys are predominately used as components in the aero/rocket engines because of their high strength-to-density ratio compared to other metallic materials.

    Abstract : Bonding techniques intended for assembling space microsystems are studied in this work. One of the largest problems in bonding pre-processed semiconductor wafers are the severe process restrictions imposed by material compatibility issues. READ MORE

  5. 5. Heat treatment of Al-Si-Cu-Mg casting alloys

    University dissertation from Göteborg : Chalmers Reproservice

    Author : Emma Sjölander; Högskolan i Jönköping.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast aluminium alloys; Heat treatment; Solution treatment; Artificial ageing; Tensile properties; Plastic deformation; Microstructure; Modelling; Plastic Deformation; Tensile Properties; Heat Treatment; Solution Treatment; Artificial Ageing;

    Abstract : Environmental savings can be made by increasing the use of aluminium alloys in the automotive industry as the vehicles can be made lighter. Increasing the knowledge about the heat treatment process is one task in the direction towards this goal. The aim of this work is to investigate and model the heat treatment process for Al-Si casting alloys. READ MORE
