  1. 1. 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

  3. 2. The Use of Gels for the Removal of Cellulose Nitrate Lacquer on Silver

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Miri Katayon; [2022-07-05]
    Keywords : agar gel; metal conservation; nanomaterials; silver coating; sustainable conservation; varnish removal;

    Abstract : The conservation of silver objects mainly constitutes addressing the issues of tarnish removal and of preventing tarnish. For decades lacquer has been used to coat silver objects in order to protect them from tarnishing. READ MORE

  4. 3. Design of passively loaded specimen for constant KI during crack growth

    University essay from KTH/Hållfasthetslära

    Author : Liisa Tofferi; [2021]
    Keywords : constant KI; passively loaded specimen; konstant KI; passivt belastad provstav;

    Abstract : Passive loading of a specimen is a relatively cheap method to use in fracture mechanical testing compared to an actively loaded specimen. For stress corrosion cracking testing it is easier to use a passively loaded specimen since the specimen easily can be placed in a specific corrosive environment. READ MORE

  5. 4. Warpage Prediction of Electronic Underfill Components During Curing

    University essay from Umeå universitet/Institutionen för fysik

    Author : David Lindblom; [2021]
    Keywords : Warpage; viscoelastic;

    Abstract : To ensure the shelf life of a semiconductor, the integrated circuits are usually embedded in an epoxy molding compound (EMC) to shield it from stress and corrosion. The EMC is a viscoelastic material and is categorized as a thermoset. Working with viscoelastic material appose a challenge due to the cure-induced warpage. READ MORE

  6. 5. Thermal Stability of Titanium and Niobium Stabilized Stainless Steel

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Oskar Darselius Berg; [2020]
    Keywords : Technology and Engineering;

    Abstract : This master thesis examined the microstructure after heat treatments in stainless steel, two conventional stainless steel (304 and 316) and two novel high temperature stainless steel. These stainless steels are for the use in high temperature heat exchangers for extended temperature range. READ MORE
