  1. 1. 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

  3. 2. The Investigation of Crack Propagation in Cortical Bone using a Phase Field Fracture Approach

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Olivia Karlsson; [2022]
    Keywords : Cortical Bone; Cortical bone microstructure; Phase field; Phase field fracture approach; Crack propagation; Technology and Engineering;

    Abstract : Human cortical bone tissue is a complex and strong composite material, with the ability to resist damage via slowing, stopping or redirecting propagating cracks. However, the ability is impaired with age. At the microscale, changes are seen both in terms of increased porosity and as changes in local material parameters. READ MORE

  4. 3. Numerical simulations of pore pressure on concrete buttress dams

    University essay from KTH/Betongbyggnad

    Author : Mohammed Abdi; Dimitirios Ntzimanis; [2022]
    Keywords : Porepressureanalysis; upliftpressure; buttressdams; drainage; groutcur- tain; rockfractures; damsafety; RIDAS.;

    Abstract : Uplift pressure is one of the most dominant forces on a dam structure. Difference in head water and tail water creates a hydraulic gradient resulting an upward oriented pressure called uplift pressure, which reduces the dam safety against sliding. READ MORE

  5. 4. Examination of a Damaged Slitting Knife using Scanning Electron Microscopy and Finite Element Simulations

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Love Öman; [2021]
    Keywords : slitting; slitting knives; damage; sem;

    Abstract : At voestalpine Precision Strip AB, the slitting process is used frequently. Slitting is a commonly applied manufacturing technique during sheet metal processing that aims to split large coils of sheet metal into narrower widths. READ MORE

  6. 5. Infrared Curing of Glass Fiber Composite Tube : Optimization of the curing cycle

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Rasmus Fredheim; [2021]
    Keywords : ;

    Abstract : This thesis has investigated the possibility of optimizing curing time by changing the energy source from a conventional oven to infrared radiation (IR) and if it is possible to achieve similar results as the company's current production of glass fiber composite tubes.   Many different parameters (time, temperature, heating rate, and rotation speed) might influence a cured composite tube's properties.
