  1. 1. Efficient FE Modeling of Large Casted Parts

    University essay from KTH/Maskinkonstruktion

    Author : Lalitha Swetha Amirapu; Haswanth Yalamanchili; [2023]
    Keywords : FE modeling; Large casted parts; Meshing techniques; Mid-surface modeling; FE-modellering; Stora gjutna delar; Meshing-tekniker; Mid-Surface modellering;

    Abstract : The design and analysis of large casted parts present significant challenges due to their complex geometry. Finite Element (FE) modeling is a vital tool for understanding the performance of casted components. However, the computational requirements associated with these parts often lead to excessive processing times and resource utilization. READ MORE

  3. 2. Approximating Damping Coefficient of Bolted Joints using the Finite Element Method

    University essay from KTH/Hållfasthetslära

    Author : Abhiroop Chatterjee; [2023]
    Keywords : ;

    Abstract : Bolted joints are important due to their energy dissipation property in structures,but the damping mechanism is also highly nonlinear and localized. The goal ofthis thesis is to develop an accurate method for modeling bolted joint dampingin large structures using finite element (FE) software. READ MORE

    Abstract : This master thesis presents a theoretical investigation of the energy and stability of interfaces in iron-carbide compounds, specifically focusing on the α-Fe/Cr7C3 system. The study aims to fill the gap in knowledge regarding the surface energetics of these interfaces using Density Functional Theory (DFT). READ MORE

  5. 4. The influence of soil modeling on the prediction of vehicle dynamics and mobility – A comparison between the Finite Element Method and a Semi[1]Empirical Model

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Jimmy Kjellqvist; [2023]
    Keywords : ;

    Abstract : This master's thesis investigated the influence of soil modeling on vehicle dynamics and mobility predictions with a focus on two different soil models implemented in Project Chrono: the Bekker-Wong model, and a Finite Element (FE) model. The primary objective is to provide insights for decision-making regarding the most suitable soil model under specific circumstances. READ MORE

  6. 5. Ab inito calculation of the formation energy of the sigma phases at 1000 Kelvin : With a five sublattice model for the ternary Iron-Chromium-Nickel system

    University essay from KTH/Materialvetenskap

    Author : Fabian Mathias Veid; [2022]
    Keywords : ;

    Abstract : This project investigates the σ-phase formation energy at 1000 Kelvin using Exact Muffin TIn Orbital (EMTO) method and considers the disordered local moment approach to handle the paramagnetism in a self-consistent manner. The sigma phase is detrimental and causes embrittlement when it occurs primarily in stainless steel and superalloys with Iron (Fe) and Chromium (Cr), which is why it is necessary to understand it better and therefore avoid it.
