  1. 1. 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.

  3. 2. Damage Analysis of Reactive Ion and Atomic Layer Etched Silicon

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Mohammad Al Abrash; [2023]
    Keywords : Technology and Engineering;

    Abstract : Dry etching is one of the most important methods of pattern transfer in nanofabrication. There are many dry etching methods, the most commonly used is reactive ion etching (RIE), that is based on a continuous supply of reactive ions and radicals generated in a radio-frequency (RF) plasma discharge.

  4. 3. Numerical method to investigate and assess the capacity of a damaged concrete structure : Using image analysis and advanced concrete modeling

    University essay from KTH/Bro- och stålbyggnad

    Author : Zakariya Benosmane; [2022]
    Keywords : Damaged Concrete Structure; Extended Finite Element Method XFEM ; Concrete Dam- aged Plasticity CDP ; Photogrammetry; Crack Detection Methods.;

    Abstract : Concrete has for decades been one of the main materials used to construct important structuressuch as dams and bridges. However, after years of service, the concrete structuresstart deteriorating and signs of damages start showing on the structure. READ MORE

  5. 4. Tensile strength reduction for insufficient thread engagement A FEM study of a wall-shoe assembly

    University essay from KTH/Hållfasthetslära

    Author : Henrik Larsson Sevon; [2021]
    Keywords : Solid Mechanics; Tensile strength; Wall-shoe; Thread engagement; Hållfasthetslära; Draghållfasthet; Väggsko; Gängingrepp;

    Abstract : The purpose of this master thesis is to determine whether or not it exist, a model that can describethe reduction in strength, due to missing threads in a bond between a bolt and nut. And how thereduction in strength might effect a wall-shoe assembly, used to connect a wall to another wall or aconcrete base plate. READ MORE
