  1. 1. Method Development & Analysis of Seals using FEM

    University essay from KTH/Maskinkonstruktion

    Author : Lovisa Svanborg Östlin; [2023]
    Keywords : FEM; guidelines; hyperelastic materials; hyperelastic material models; method development; seals; FEM; riktlinjer; hyperelastiska material; hyperelastiska materialmodeller; metodutveckling; tätningar;

    Abstract : Hyperelasticity is a significant property of rubber, taken advantage of in engineering applications. A common application is the use of seals to prevent fluid transfer (liquid or gas) between solid regions. Volvo CE is often depending on external supplier when developing seals. READ MORE

  3. 2. Nitrogen legacies in agricultural catchments : an analysis of 170 years of nitrogen legacies data in four Swedish agricultural catchments

    University essay from SLU/Dept. of Soil and Environment

    Author : Laura-Ainhoa Prischl; [2023]
    Keywords : nitrogen mass balance; nitrogen surplus; land use trajectories; hysteresis effect; water quality; agriculture; nitrogen surplus; land use trajectories; hysteresis effect; water quality; agriculture;

    Abstract : Despite the enforcement of legislation and application of measures, nitrogen (N) levels continue to be high in streams. One of the reasons for the low N reduction, is the legacy accumulation of N. READ MORE

  4. 3. Dynamic Modelling of a Fluidic Muscle with a Comparison of Hysteresis Approaches

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Tess Antonsson; [2023]
    Keywords : Mechatronics; Soft Actuators; Pneumatic Artificial Muscles; Dynamic Modelling; Hysteresis; Maxwell-Slip Model; Generalised Bouc-Wen Model; Mekatronik; Mjuka Ställdon; Pneumatiska Artificiella Muskler; Dynamisk Modellering; Hysteres; Maxwell-Slip Modell; Generaliserad Bouc-Wen Modell;

    Abstract : n recent years, there has been a surge in interest and research into the utilisation of soft actuators within the field of robotics, driven by the novel capabilities of their inherently compliant material. One such actuator is the Pneumatic Artificial Muscle (PAM) which offers a high power-to-mass ratio, compliance, safety, and biological mimicry when compared to their traditional counterparts.

  5. 4. Development of MOKE spectrometer

    University essay from Uppsala universitet/Materialfysik

    Author : Sebastian Åberg; [2023]
    Keywords : MOKE; Spectroscopy;

    Abstract : The magneto-optical Kerr effect (MOKE) describes the change in polarization of light reflected from a magnetic surface. This change is proportional to the magnetization and depends on the wavelength of light. Because of these properties, MOKE has found use as a tool to probe magnetism in matter. READ MORE

  6. 5. Preparation and Characterization of Tb-Co Magnetic Films

    University essay from Uppsala universitet/Materialfysik

    Author : Roméo Beignon; [2022]
    Keywords : Thin Film; TbCo; Out-of-Plane Anisotropy; Magnetic Domains;

    Abstract : Thin films of terbium-cobalt alloy have been deposited by magnetron sputtering. They exhibit an out-of-plane magnetic anisotropy that may result in elongated domains. The effect of thicknesses and compositions on the domain structure has been studied systematically. READ MORE
