  1. 1. Industrial Sheet Metal Forming Simulation with Elastic Dies

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik; Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Markus Lind; Viktor Sjöblom; [2018]
    Keywords : Elastic Stamping Dies; FEA; LS-Dyna; Sheet Metal Forming; Structural Analysis;

    Abstract : As part of the development process for new stamping dies, in the automotive sheet metal forming (SMF) industry, the majority of all forming operations are simulated with the Finite Element Method (FEM) before the dies are manufactured. Today, these simulations are conducted with rigid tools under the assumption that there are no tool deformations.

  2. 2. Validation of blast simulation models via drop-tower tests

    University essay from Umeå universitet/Institutionen för fysik

    Author : Joakim Rydman; [2018]
    Keywords : Screw; bolt; screw joint; bolted connection; simulation; model; FEM; FEA; finite element; LS-DYNA; drop-tower tests; validation;

    Abstract : This study aims to validate a screw joint simulation model used by BAE Systems in LS-DYNA during blast simulations. It is important that the screw joint simulation model is physically correct, since the simulation results can influence major design decisions. READ MORE

  3. 3. Study of a Body Subjected to a Vertical Drop into Water – Experiment and Simulations

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

    Author : Josefin Andersson; Monika Englund; [2018]
    Keywords : ;

    Abstract : In computational fluid dynamics (CFD), the computational domain can be discretized using mesh- based methods or particle based methods. During this project; a CFD method that uses smoothed particle hydrodynamics (SPH), in which the computational domain is discretized by particles, is modelled and compared to mesh-based CFD methods, in which the domains are broken into a set of discrete volumes.

  4. 4. Finite Element Analysis of Osseointegrated Transfemoral Implant : Indentification of how the Length of Implant Affects the Stress Distribution in Cortical Bone and Implant

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Anna Pogosian; [2018]
    Keywords : Osseointegrated; Implant; Transfemoral; Finite Element Methods;

    Abstract : An alternative method of conventional prosthesis is  osseointegrated transfemoral implant, in where the prosthesis is fixated directly to the bone. The benefits with this system is increased range of motion, sensory feedback and reduced soft tissue problem. READ MORE

  5. 5. Simulation of the anisotropic material properties in polymers obtained in thermal forming process

    University essay from Högskolan i Jönköping/JTH, Produktutveckling; Högskolan i Jönköping/JTH, Produktutveckling

    Author : Ali Bazzi; Andreas Angelou; [2018]
    Keywords : Plastics; Acrylonitrile Butadiene Styrene; Vacuum Thermoforming; Strain Induced Anisotropy; Hyperelasticity; Ogden; Barlat; LS-DYNA; FEM Analysis; Forecasting Material Properties; Thickness Distribution; Process Simulation;

    Abstract : In an attempt to improve the quality in finite element analysis of thermoformed components, a method for predicting the thickness distribution is presented. The strain induced anisotropic material behaviour in the amorphous polymers of concern is also taken into account in the method. READ MORE
