  1. 31. A 3D Sliding Bearing Finite Element Based on The Bouc-Wen Hysteretic Model : Mathematical modelling and numerical implementation

    University essay from KTH/Bro- och stålbyggnad

    Author : Sicong Wei; [2020]
    Keywords : high-speed railway; nonlinear dynamics; bridge bearings; friction; hysteresis; secondary development; damping;

    Abstract : Bridge bearing is an essential component with the function of connecting the superstructure and substructure of the bridge, transmitting load and providing movability to the superstructure. Under dynamic conditions, the internal friction of bridge bearing dissipates the vibration energy and therefore reduces the dynamic response of the bridge. READ MORE

  3. 32. Analysis of stellar spectra with machine learning

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Alvaro Segovia Otero; [2020]
    Keywords : Galactic Archaeology; machine learning; chemical abundances; FGK stars; Physics and Astronomy;

    Abstract : Researchers in the field of Galactic Archaeology have entered the era of industrial revolution. Upcoming surveys are planning on observing tens of millions of stars and high precision and accuracy must be ensured when deriving their stellar parameters and elemental abundances. READ MORE

  4. 33. Modelling, Evaluation and Assessment of Welded Joints Subjected to Fatigue

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Prajeet Rajaganesan; [2020]
    Keywords : Welded joints; Fatigue Assessments; Hot Spot method; Python Automation; Post-processing; Abaqus;

    Abstract : Fatigue assessment of welded joints using finite element methods is becoming very common. Research about new methods is being carried out every day that show a more accurate estimation of the fatigue life cycle than the previous ones. READ MORE

  5. 34. Modelling and Mechanical Analysis of Continuously Transposed Conductor

    University essay from KTH/Hållfasthetslära

    Author : Haicheng Hu; [2020]
    Keywords : CTC; modelling; finite element analysis; epoxy coating; compliance; torsional rigidity; CTC; modellering; FEM; epoxibeläggning; komplians; böjstyvhet; vridstyvhet;

    Abstract : As the CTC (transposed continuously conductor) is widely accepted as the cable used in transformers, mechanical analysis of CTC under different load cases is in need. This paper introduces a new method of creating detailed CTC models automatically in Comsol Multiphysics and the models are applied for conducting FEA (Finite Element Analysis) for different load cases of practical importance.

  6. 35. Behavior prediction of concrete dams

    University essay from KTH/Betongbyggnad

    Author : Isak Nilsson; Leonard Sandström; [2020]
    Keywords : Concrete dams; dam monitoring; dam safety; measurement evaluation; databased models i;

    Abstract : As many dams were built around 1950, the expected life span of these dams are about tobe reached. With this, the need for monitoring and increased understanding of the damsstructural integrity increases. In order to prevent failures, two warning signals are defined;alert and alarm. READ MORE
