  1. 1. Analysis of a shape morphing structural battery: manufacturing, analytical modeling and numerical simulation

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Alfredo Bici; [2023]
    Keywords : ;

    Abstract : A reduction in the global use of fossil fuels is necessary when striving for a more sustainable future. One key strategy in the transition from fossil fuels is electrification. This strategy is particularly prominent within the transport sector, where more efficient ways to store electric energy are being pursued. READ MORE

  3. 2. Fracture simulation with a hyperelastic phase field model

    University essay from KTH/Hållfasthetslära

    Author : Adrien Fradet; [2023]
    Keywords : Fracture; Phase field modeling; Hyperelasticity; Brott; fasfält-methoden; hyperelasticite;

    Abstract : The phase field method is a versatile tool to study crack initiation and propagation in systems with complex geometries. Based on a variational formulation of the equilibrium equations, the sharp crack topology is regularized by a crack with diffusive edges and the damage is described by a continuous phase field variable.

  4. 3. 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

  5. 4. Uncertainties in the use of synthetic CT (sCT) for daily online adaptive radiotherapy for lung cancer

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Johansson Vivika; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Background and purpose: Cone Beam Computed Tomography (CBCT) based online adaptive radiotherapy (oART) has been clinically implemented for several anatomical sites worldwide. However, random and abrupt anatomical changes with large density alterations can occur in lung patients, leading to uncertainties with synthetic computed tomography (sCT) and dose calculation.

  6. 5. Finite Element Macro-modeling of a Historical Masonry Building : Influence of Isotropic vs Anisotropic Plastic Material Model Assumption in Static Analysis

    University essay from KTH/Bro- och stålbyggnad

    Author : Madeleine Olsson; Maja Gustavsson; [2023]
    Keywords : ;

    Abstract : In this study, a macro-modeling strategy is implemented in a bearing wall with arch openings in an existing historical masonry building. This is to investigate what differences and similarities can be observed from the assumption of an orthotropic versus an isotropic constitutive material model. READ MORE
