  1. 1. On Low-Cycle Fatigue

    Författare :Johan Tryding; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The experimental results presented confirm the anticipation that it is extremely important not to confuse the concept of 'static loading' with the one of 'monotonic loading'. In principle three different crack configurations were investigated in: edge-cracks, internal flaws and surface cracks. LÄS MER

  2. 2. Comparability of Railway Rail Steels Low Cycle Fatigue Behaviour

    Författare :Martin Schilke; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway rail steel; strain energy density; Low cycle fatigue;

    Sammanfattning : Several different kinds of steel are used for railway rails. From simple pearlitic steels for rarely used tracks over premium pearlitic steels for high performance lines to special bainitic, martensitic and austenitic steels for switches and crossings. Most of these steels have been trial and error developed over time in track. LÄS MER

  3. 3. Low Cycle Fatigue and Thermo-Mechanical Fatigue of Uncoated and Coated Nickel-Base Superalloys

    Författare :Svjetlana Stekovic; Torsten Ericsson; Hael Mughrabi; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; AMDRY997; CMSX-4; SCB; Thermo-Mechanical Fatigue; Coatings; Gas Turbine; IC1; IC3; IN792; Low Cycle Fatigue; Nickel-Base Superalloys; RT22; Materials science; Teknisk materialvetenskap;

    Sammanfattning : High strength nickel-base superalloys have been used in turbine blades for many years because of their superior performance at high temperatures. In such environments superalloys have limited oxidation and corrosion resistance and to solve this problem, protective coatings are deposited on the surface. LÄS MER

  4. 4. Interfacial Reactions and Low Cycle Fatigue of Lead-Free Solders for Electronic Packaging

    Författare :Peng Sun; Chalmers University of Technology; []
    Nyckelord :Interfacial Reactions and Low Cycle Fatigue of Lead-Free Solders for Electronic Packaging; Low Cycle Fatigue; Intermetallic Compounds; Lead-Free Solders; Finite Element Simulation;

    Sammanfattning : Two key technologies used by the electronics industry are chip technology and packaging technology. Solder plays a crucial role in both of them. During the last decade, there has been a strong worldwide environmental movement towards lead-free electronic products. LÄS MER

  5. 5. Low Cycle Fatigue Reliability and Interfacial Reaction of Lead-free Solder Joints for Electronic Packaging

    Författare :Sun Peng; Chalmers University of Technology; []
    Nyckelord :Finite Element Simulation; Reliability; Intermetallic Compounds; Lead-free Solder; Low Cycle Fatigue;

    Sammanfattning : Two key technologies in electronics industry are chip technology and packaging technology. Solder plays a crucial role in the assembly and interconnection in the electronic packaging industry. As a joint material, solder provides electronic, thermal and mechanical continuity. LÄS MER
