  1. 1. Modelling of nanometric cutting in metals using MD simulations

    Magister-uppsats, Lunds universitet/Mekanik

    Författare :Damien Gautier; [2022]
    Nyckelord :Nanometric cutting; Molecular Dynamics; Technology and Engineering;

    Sammanfattning : This master thesis project has been done within the Mechanics department of Lunds Tekniska Högskola (LTH). It studies the nanometric cutting process of a single crystal copper workpiece by a cubic diamond tool using Molecular Dynamics (MD) simulations on the software LAMMPS. LÄS MER

  3. 2. Exact eigenstates of the Inozemtsev spin chain

    Master-uppsats, KTH/Fysik

    Författare :Simon Lentz; [2021]
    Nyckelord :Theoretical physics; Mathematical physics; quantum mechanics; many-body problems; spin chain; Inozemtsev; Calogero-Sutherland; Teoretisk fysik; Matematisk fysik; kvantmekanik; mångpartikel problem; spinnkedjor; Inozemtsev; Calogero-Sutherland;

    Sammanfattning : This thesis deals with the following question: are there more eigenfunctions, other than the already known eigenfunctions, of the spin chain with elliptic interactions known as the Inozemtsev spin chain? The Inozemtsev spin chain interpolates between two quantum integrable spin chains, theHeisenberg spin chain and the Haldane-Shastry spin chain. Therefore it is interesting to explore eigenfunctions of the Inozemtsev spin chain in greater detail. LÄS MER

  4. 3. Compression Characteristics of Elastomer Elements

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Rahul Nagaraj Dixit; [2021]
    Nyckelord :Continuum mechanics; Hyperelasticity; Mooney Rivlin; Rack and Pinion; Kontinuummekanik; Hyperelasticitet; Mooney Rivlin; Kuggstångsväxel;

    Sammanfattning : Compression of elastomer elements are nonlinear due to the cross-linked molecular structure owing to a property known as hyperelasticity. Hyperelasticity is defined as the nonlinear stress-strain behavior shown by rubber like materials which can be strained up to a range of 700% in tension and up to 40% in compression. LÄS MER

  5. 4. FE-Modelling of a Joint for Cross-Laminated Timber

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Linus Ekhagen; [2021]
    Nyckelord :cross-laminated timber; fe-modelling; continuum damage mechanics; fracture; korslimmat trä; fe modellering; skademekanik; brott;

    Sammanfattning : Woodbe Engineering AB is a freshly started company that has developed a new type of joint for cross-laminated timber (CLT). The joint does not include any metallic fasteners, which improves sustainability, the ergonomics for the workers and time efficiency. LÄS MER

  7. 5. Evaluation of Peridynamics and Its Application in Harmonic-Structured Material Simulations

    Master-uppsats, Lunds universitet/Mekanik

    Författare :Theodor de Sousa; [2020]
    Nyckelord :peridynamics; peridigm; harmonic-structured materials; computational mechanics; fracture modelling; Technology and Engineering;

    Sammanfattning : Materials are constantly sought to be improved in different manners. Two of the most common characteristics to improve are strength, and ductility. Historically, materials are modified homogeneously to achieve improvement, while the past century has also seen composite materials becoming standard-issue within various industries. LÄS MER
