  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. Evaluation of Crack Depth Meter - An investigation of the crack depth meters possibilities and limitations for commonly occurring damage mechanisms

    University essay from KTH/Hållfasthetslära

    Author : Alfred Norberg; [2023]
    Keywords : Crack depth measurement; RMG 4015; ACPD; Damage Mechanism; Evaluation; FEM Simulation; Sprickdjupsmätning; RMG 4015; ACPD; Skademekanism; Utvärdering; FEM-simulering;

    Abstract : In this master thesis, the accuracy of the crack depth meter RMG 4015 was evaluated for different types of cracks with various damage mechanisms. In total, 61 crack depth measurements were conducted with the crack depth meter on 56 cracks which were located in the 23 different test pieces supplied by Kiwa. READ MORE

  4. 3. Crack propagation in 3D-printed PLA

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Johan Stenborg; Amaro Ramirez Flores; [2022]

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Gunnar Dufwa; [2022]
    Keywords : Hydrogen embrittlement; carbide; finite element method; dislocation dynamics;

    Abstract : Hydrogen embrittlement is a well-known source of cracking in metallic mechanical elements. This work studies the influence of hydrogen and carbides on the crack formation in a castnickel-alloy-component in a selective catalytic reduction system. READ MORE

  6. 5. Fatigue Crack Growth Analysis in Python algorithm with Finite Element Methods : Numerical Simulation of Fatigue Crack Growth

    University essay from Karlstads universitet

    Author : Hasan Majid; [2022]
    Keywords : ;

    Abstract : The goal of this thesis was to construct and develop a python-based finite element computer program for the evaluation of fatigue crack growth rate in notched metallic rods. The simulation was done by implementing elastic stress theory and linear elastic fracture mechanics techniques. READ MORE
