  1. 6. Bearing strength and failure behavior of hybrid composite laminates.

    Master-uppsats, Linköpings universitet/Konstruktionsmaterial

    Författare :Hanasoge Saraswathi Deepthi Prasad; [2020]
    Nyckelord :Thin ply; composite materials; bearing strength;

    Sammanfattning : Composite layups have been continuously used over many years in various applications. It is necessary to optimize its composition by studying various parameters influencing the mechanical properties and studying the failure behavior. LÄS MER

  3. 7. Effects of Austempering Process on Mechanical Behavior Properties of Compacted Graphite Iron

    Master-uppsats, Högskolan i Jönköping/JTH, Material och tillverkning; Högskolan i Jönköping/JTH, Industriell produktutveckling, produktion och design

    Författare :INAMUL HASSAN; [2019]
    Nyckelord :AusCGI;

    Sammanfattning : The thesis paper here focuses on the effects of the austempering temperature (TA) and the austempering time (tA) on the unalloyed fully ferrite Compacted Graphite Iron (CGI), to obtain improve in mechanical properties and the study of the microstructure. The unalloyed CGI samples were austenitised at 850oC for 60 and 90 min and were then heat treated at 275, 325 and 375oC with different holding times at 30,60,90, and 120 mins. LÄS MER

  4. 8. Fractography, mechanical and structural analysis of trabecular bone from the femoral head of human cadavers

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Christina Rönngren; [2017]
    Nyckelord :Technology and Engineering;

    Sammanfattning : A lowered mineral density in the skeletal bones may indicate osteoporosis and an increased risk of fragility fractures. However, lower bone mass does not reveal the whole truth about the status of the bone quality. LÄS MER

  5. 9. Hydrogen-assisted stress corrosion cracking of high strength steel

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Rohollah Ghasemi; [2011]
    Nyckelord :Hydrogen embrittlement; hydrogen induced cracking; stress corrosion cracking; high strength steel; uniform corrosion; SSRT; hydrogen charging; fractography; hydrogen degradation;

    Sammanfattning : In this work, Slow Strain Rate Test (SSRT) testing, Light Optical Microscopy (LOM) and Scanning Electron Microscopy (SEM) were used to study the effect of micro-structure, corrosive environments and cathodic polarisation on stress corrosion cracking (SCC) of two grades of high strength steels, Type A and Type B. Type A is manufactured by quench and tempered (Q&T) method. LÄS MER
