  1. 11. Investigation of microstructure and mechanical properties of 3D printed Nylon

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Gustav Engkvist; [2017]
    Keywords : Plastic; Nylon; Multiscale; Microstructure; Mesostructure Thermal distortion; Shape distortion; 3D printing; Additive manufacturing; Fused deposition modelling; FDM;

    Abstract : This thesis presents a multiscale investigation and characterization of additive manufactured Polyamide material using fused deposition modelling technique. Manufacturing was performed using Markforgeds – Mark one 3D printer. READ MORE

  3. 12. Offset modeling of shell elements : A study in shell element modeling using Nastran

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : David Klarholm; [2016]
    Keywords : Offset shell elements; finite element; Nastran; shell element modeling; Rigid body connection; Rigid links; Kirchhoff shells; Multipoint constraint;

    Abstract : At Saab Aerostructures they are manufacturing a lot of parts for Airbus and Boeing. When these components are investigated using finite element analysis four-node Kirchhoff shell elements and a very fine mesh is often used. READ MORE

  4. 13. Second-order FE Analysis of Axial Loaded Concrete Members According to Eurocode 2

    University essay from KTH/Betongbyggnad

    Author : Nessa Yosef Nezhad Arya; [2015]
    Keywords : Second-order; nonlinear; slender reinforced concrete column; ABAQUS; FE analysis; curvature method; nominal stiffness method; eccentrically loaded; benchmark experiment; parametric study; Andra ordningens effekt; icke-linjär; slank armerad betongpelare; ABAQUS; FE-modellering; krökningsmetoden; styvhetsmetoden; excentrisk last; utvärderingsförsök; parameterstudie;

    Abstract : A nonlinear finite element analysis was performed for an axial loaded reinforced concrete column subjected to biaxial bending taking into account second-order effects. According to Eurocode there are two ways to take second-order effects into consideration: nonlinear FE analysis and hand calculation based on the simplified methods explained in Eurocode 2.

  5. 14. Dual-Probe Shear Wave Elastography in a Transversely Isotropic Phantom

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Gioia Bassan; [2015]
    Keywords : Shear Wave Elastography; Transversely isotropic phantom;

    Abstract : Shear Wave Elastography (SWE) is an ultrasound based technique which is able to measure tissue stiffness through the speed of induced shear waves. Tissue stiffness is often related to pathological conditions and detecting mechanical changes can help the recognition of potential diseases. READ MORE

  6. 15. Structural strength of work boatsand high speed crafts with floatingframes

    University essay from KTH/Marina system

    Author : Jon Englund; [2009]
    Keywords : ;

    Abstract : This thesis investigates the usage of floating frames in boats. A floating frame is a transverse frame fittedto the longitudinal stiffener flanges without contact with the shell plating, as opposed to the traditionalfixed frame which is welded to the shell plating with the stiffeners most commonly fitted through cut outsin the frame.
