  1. 1. Structural responses due to underwater detonations : Validation of explosion modelling methods using LS-DYNA

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Gustav Blomgren; Ebba Carlsson; [2023]
    Nyckelord :Underwater explosion; UNDEX; detonation; fluid structure interaction; FSI; SSA; S-ALE; shock-wave; explosive; PETN; explosive modelling; Sub-Sea Analysis; Structured ALE; Arbitrary Lagrangian Euler; Multi Material Arbitrary Lagrangian Euler; MMALE; LS-DYNA;

    Sammanfattning : Modelling the full event of an underwater explosion (UNDEX) is complex and requires advanced modelling methods in order to achieve accurate responses. The process of an UNDEX includes a series of events that has to be considered. LÄS MER

  4. 3. Multicolor 3D printing : An analysis of the characteristics of multicolor 3Dprinting

    Kandidat-uppsats, KTH/Mekatronik

    Författare :Davron Patkhullaev; Yonas Melake; [2021]
    Nyckelord :Mechatronics; 3D printer; Arduino Mega; Diamond Hotend; Marlin; Mekatronik; 3D printer; Arduino Mega; Diamond Hotend; Marlin;

    Sammanfattning : 3D printing has risen in popularity due to its capabilities which enable rapid prototyping and printing structures that were impossible to produce before and partially because of technological development in recent years. Most low-cost printers, based on the fused filament fabrication process, are capable of printing a single filament at a time that limits and complicates multicolor and multi-material 3D printing.
