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. Error propagation in nuclear models

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Artis Mucenieks; [2023]
   Keywords : Physics and Astronomy;

   Abstract : In this thesis we perform error analysis of a nuclear model based on density-functional theory developed in Lund. The Lund model allows us to perform calculations of nuclear spectra more efficiently by constructing a simple effective Hamiltonian reproducing the quadrupole deformation and pairing interaction strength parameters of a spherical Hartree-Fock reference functional.

5. 4. FEM analysis of existing buildings during renovation

   University essay from KTH/Hållfasthetslära

   Author : Agnes Nyberg; [2023]
   Keywords : Sturegallerian; Räumlich Finite Element Method; Euro code; Masonry; Steel amplifier; Sturegallerian; Räumlich Finita Element Metod; Eurokoder; Murverk; Stål förstärkning;

   Abstract : In this masters thesis the aim was to investigate a part of Sturegallerian in Stockholm to be reconstructed. The reconstruction did implicate that openings were to be established in an already existing masonry wall. READ MORE

6. 5. Automatic Detection of Structural Deformations in Batteries from Imaging data using Machine Learning : Exploring the potential of different approaches for efficient structural deformation detection

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Maira Khan; [2023]
   Keywords : CT scan; electrode peaks; jelly roll; keypoints; structural deformation; traditional computer vision; deep neural network; CT-skanning; elektrodtoppar; gelérulle; nyckelpunkter; strukturell deformation; Traditionellt datorseende; djupt neuralt nätverk;

   Abstract : The increasing occurrence of structural deformations in the electrodes of the jelly roll has raised quality concerns during battery manufacturing, emphasizing the need to detect them automatically with the advanced techniques. This thesis aims to explore and provide two models based on traditional computer vision (CV) and deep neural network (DNN) techniques using computed tomography (CT) scan images of jelly rolls to ensure that the product is of high quality.
