  1. 1. FE Modeling of Cushion 3D Motion for Sheet Metal Forming Simulation

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Jagdish Jadhav; [2019]
    Keywords : Finite Element analysis; contact pressure; sheet metal forming; LS-DYNA.;

    Abstract : Nowadays FE-simulations for sheet metal forming process are used to reduce the tryout phase in automotive industries. But the complex forming simulation processes are very challenging. One of the challenges is to create an FE-model which can be used to analyze the effects of cushion motion on the forming process. READ MORE

  2. 2. Modeling and Analysis of the Shot Peening Process : a Study of the Residual Stresses in an Insert using the Finite Element Method

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Hamid Torkaman; [2018]
    Keywords : Shot peening; Residual stresses; Cutting tool inserts; Post-coating treatment; Coated cemented carbide;

    Abstract : Cutting tool inserts are often coated with thin layers either through chemical vapor deposition (CVD) or physical vapor deposition (PVD) processes. In order to have a better wear resistance cutting tools are mostly subjected to post-coating treatment processes. READ MORE

  3. 3. Prediction of fracture propagation in human femur using the Finite Element Method

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Frida Bengtsson; [2018]
    Keywords : Technology and Engineering;

    Abstract : Hip fractures constitute a major problem, both in terms of a lower life quality for the people affected and socio-economical factors. Osteoporosis is a medical condition, defined by decreased bone mass, which results in a more fragile bone structure and a higher risk for fractures. Osteoporosis accounts for a cost of € 1.

  4. 4. Train Induced Vibration Analysis of an End-frame Bridge : Numerical Analysis on Sidensjövägen

    University essay from KTH/Bro- och stålbyggnad; KTH/Bro- och stålbyggnad

    Author : Niklas Wiberg; Jasmin Halilovic; [2018]
    Keywords : Accelerations; Dynamics; End-frame bridge; FE-modeling; Frequency response function; High-speed railway; Soil structure interaction; Train induced vibrations; 2D 3D;

    Abstract : Higher speeds and higher capacity will cause the Swedish rail network to be exposed to disturbing dynamic effects. Higher speeds cause higher vertical acceleration levels of the bridge deck. In this thesis, a numerical analysis of a three span end-frame bridge subjected to train induced vibrations is performed.

  5. 5. Linear and non-linear FE-analysis of cracking behavior of wing walls in integral bridges

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Andreas Ekman; Christoffer Sandin; [2018]
    Keywords : Non linear FE-modelling; Concrete Damage Plasticity; Wing wall; Crack propagation; Serviceability Limit State; Slab Frame Bridge; Technology and Engineering;

    Abstract : Wing walls on slab frame integral bridges has traditionally been designed for mainly earth pressure and its self-weight. It has also been designed separately from the rest of the bridge. Traditionally no 3D effects have been considered in the design of the wing walls. READ MORE
