  1. 21. Thermoplasticity in topology optimization based on finite strain

    University essay from Lunds universitet/Hållfasthetslära

    Author : Anders Engström; [2017]
    Keywords : FEM; topology optimization; finite deformations; thermoplasticity; Technology and Engineering;

    Abstract : A thermoplastic finite strain model is used to model heat generation due to plastic work. Isotropic hardening is used, where the mechanical dissipation acts as heat source in the heat equation. The multiplicative split of the deformation gradient makes it possible to separate plastic and elastic effects. READ MORE

  3. 22. Minimizing Cooling Time for Diamond Anvil Cell Under High Pressure

    University essay from Lunds universitet/Mekanik

    Author : Martin Edung; [2017]
    Keywords : Diamond Anvil Cell; FEA; FEM; Structural; Transient; Temperature; Ansys; Ansys WB; Machine Drawings; ESS; European Spallation Source; Technology and Engineering;

    Abstract : The main goal of the project was to decrease the cooling time of a diamond anvil cell (DAC) by modifying an existing design. Modifications included change of materials, overall dimensions and a significant reduction of mass together with additional suggestions for decreased cool time. READ MORE

  4. 23. Spacecraft dynamic analysis and correlation with test results : Shock environment analysis of LISA Pathfinder at VESTA test bed

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Beata Iwona Kunicka; [2017]
    Keywords : FEA FEM; finite element analysis; finite element method; mechanical analysis; structural analysis; dynamic analysis; computational dynamic analysis of structures; shock analysis; shock environment; shock test; shock test campaign; spacecraft dynamic analysis; MSC Nastran; MSC Patran; Dynaworks; Shock Response Spectrum; SRS; space engineering; space science and technology; mechanical engineering; structural engineering; analysis optimisation; analysis parametrisation; mechanical wave propagation; shock propagation; damping; hysteretic damping; viscous damping; structural damping;

    Abstract : The particular study case in this thesis is the shock test performed on the LISA Pathfinder satellite conducted in a laboratory environment on a dedicated test bed: Vega Shock Test Apparatus (VESTA). This test is considered fully representative to study shock levels produced by fairing jettisoning event at Vega Launcher Vehicle, which induces high shock loads towards the satellite. READ MORE

  5. 24. Design of an innovative chassis made in bio-composite

    University essay from KTH/Lättkonstruktioner

    Author : Benjamin Perez; [2016]
    Keywords : ;

    Abstract : The present master thesis concludes the Vehicle engineering program followed at KTH University in Sweden and my mechanical engineer formation at Arts & Métiers Paritech in France. The use of composites materials is nowadays widespread and no longer only restricted to high added value objects. READ MORE
