  1. 11. Mechanical Engineering for Electronics.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Loïc Was; [2012]
    Keywords : ;

    Abstract : Schlumberger drilling tools are exposed to very hard loading conditions (shocks, vibrations, thermal cycling) while performing a job. As these tools are full of electronics, issues can quickly come from electronics failure. Mechanisms of failure occurring in electronics are very complex but can be predicted in some cases.

  3. 12. Comparison of stress behaviour in thermal barrier coatings using FE analyses

    University essay from Institutionen för ingenjörsvetenskap

    Author : Tobias Hansson; Kristoffer Skogsberg; [2012]
    Keywords : TBC; TGO; FE Analysis; microstructure; surface rougness; residual stresses;

    Abstract : The objective of this thesis project was to compare the stress behaviour in thermal barrier coatings (TBCs) with FE analyses in both 2D and 3D. The main focus was to analyse the vertical stresses in the topcoat (TC) and how they varied in relation to different thicknesses of the thermally grown oxide (TGO), spraying methods of the bondcoat (BC) and the topography of the BC.

  4. 13. Evaluation of HMA fracture mechanics-based thermal cracking model.

    University essay from KTH/Transportvetenskap

    Author : Sen Lin; [2011]
    Keywords : Hot Mix Asphalt; Low temperature cracking; HMA fracture mechanics; Thermal cracking model; SuperPave IDT; Thermal Stress Restrained Specimen Test;

    Abstract : Low temperature cracking is an important form of asphalt pavement deterioration in cold regions. The cracks develop when thermally induced stresses exceed the fracture resistance of the asphalt pavement. READ MORE

  5. 14. ECC-D4 Electostatic Oil Cleaner Design for Heavy-Duty Gas Turbine Applications

    University essay from Mekanisk värmeteori och strömningslära

    Author : Murat Gorur; [2010]
    Keywords : Energy System; Electrostatic Cleaner; Gas Turbines; Electrostatic Field; Turbine Oil; Oil Clenaer;

    Abstract : The turbine technology improvements from 1980 onwards have considerably increased mechanical and thermal stresses on turbine oils which, cause oil oxidation and thereby turbine oil degradation (Livingstone et al., 2007; Sasaki & Uchiyama, 2002). READ MORE

  6. 15. Towards a Uniform Fracture Mechanics-Based Framework for Flexible Pavement Design

    University essay from KTH/Väg- och banteknik

    Author : Prabir Das; [2009]
    Keywords : Crack growth; Low temperature cracking; Fracture mechanics; Dissipated creep strain energy; Asphalt pavements; Energy Ratio;

    Abstract : Cracking is an important potential failure mechanism for pavement structures. By combining a strain energy-based fracture criterion with conventional fracture mechanics based on the Energy Ratio (ER) concept, crack growth in asphalt can be investigated, and a low temperature Thermal Cracking model (TCMODEL) can be introduced.
