  1. 1. Thermal fatigue and soldering experiments of additively manufactured hot work tool steels

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Henrik Andersson; [2018]
    Keywords : Additive manufacturing; 3D printing; Hot work tool steel; Thermal fatigue; heat checking; Die casting; Soldering; AISI H13; Additiv tillverkning; 3D printing; Varmarbetsstål; Termisk utmattning; Värmesprickor; Pressgjutning; Soldering; AISI H13;

    Abstract : Modern manufacturing processes are under a never ending evolvement. Lowered manufacturing costs, higher part quality, shorter lead times and lower environmental impact are some important drivers for this development. Aluminum die casting is an effective and attractive process when producing components for e.g. READ MORE

  2. 2. Fatigue Life Analysis of Weld Ends : Using FE-Calculations and Mechanical Testing

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Victor Ljungdahl; [2018]
    Keywords : Comparison; Effective notch method; Testing; Weld End; Jämförelse; Effective notch metoden; Provning; Svetslut;

    Abstract : Fatigue life estimation of welds is a complex issue since the characteristics of each weld are unique depending on load case, geometry and properties. Fatigue life estimation on weld ends is limited and often the weakest point of a weld. READ MORE

  3. 3. A tramming concept for a mechanical rock excavation machine

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Sara Blomqvist; [2015]
    Keywords : Tramming; Propelling; Mechanical rock excavation; Tramming; Propellering; Mekanisk bergavverkning;

    Abstract : This report is the result of a thesis project at KTH in cooperation with Svea Teknik AB and Atlas Copco Mining and Rock Excavation. Atlas Copco is currently developing a family of machines for mechanical rock excavation. All machines in the family have two propulsion methods. READ MORE

  4. 4. Thermo-mechanical fatigue of castiron for engine applications

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Niklas Collin; [2014]
    Keywords : Thermo-mechanical fatigue; TMF; CGI; LGI; fatigue; thermal strain.; Termomekanisk utmattning; TMF; CGI; LGI; termisk töjning.;

    Abstract : In an engine component the repeated start-stop cycles cause temporal and local inhomogeneous temperatures, which in turn lead to a type of low-frequency loading, plastic deformation and eventually failure due to thermo-mechanical fatigue. Simultaneously, high-frequency mechanical loading arises from the cyclic combustion pressure and from road induced vibrations. READ MORE
