  1. 1. Study of defects in PV modules : UV fluorescence and Thermographic photography for Photovoltaics (PV) Field Application

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik; Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Sophie Nylund; Zahra Barbari; [2019]
    Keywords : UV fluorescence; IR thermography; defects in PV modules; delamination; discoloration; hotspots; snail trails; cracks; fault in bypass diode; non-functioning cell in PV;

    Abstract : For a PV plant it is of fundamental importance that the operation of the PV modules is free from faults or at least that the faults can be detected early, to ensure efficient electricity production. Some defects such as cracks can be seen in visible light while microcracks and damage to the silicon material can only be seen through special lighting. READ MORE

  3. 3. Residual stresses and distortions in austenitic stainless steel 316L specimens manufactured by Selective Laser Melting

    University essay from Högskolan Väst/Avdelningen för svetsteknologi (SV)

    Author : Henrik Nöbauer; [2018]
    Keywords : Residual Stresses; Distortions; SLM; Selective Laser Melting; 316L; X-ray diffraction; XRD; ESPI; Hole drilling;

    Abstract : Residual stresses are one of the major challenges in additive manufacturing of metallic materials today. They are induced during manufacturing because of the rapid local heating and cooling and may cause distortions, cracking and delamination between layers. READ MORE

  4. 4. Failure Modeling of Curved Composite Beams : Numerical Modeling of Failure Onset and Propagation in L-Profile Beams

    University essay from KTH/Lättkonstruktioner

    Author : Suhas Gururaj Shetty; [2018]
    Keywords : ;

    Abstract : The high strength/stiffness-to-weight ratio that composite materials exhibit has led to the utilization of composites as alternative to traditional materials in weight-critical applications. However, the highly anisotropic nature of composites renders the strength prediction under complex loading challenging. READ MORE

  5. 5. Recyclability by Design of Flexible Packaging

    University essay from Lunds universitet/Förpackningslogistik

    Author : Rafael Ferrándiz Martínez; [2018]
    Keywords : flexible packaging; recyclability; shelf-life; barrier film; structures; Technology and Engineering;

    Abstract : This research has established a different approach towards a better design in packaging development for the Early Life Nutrition portfolio of Danone Nutricia Research. During this study, the value chain of plastic flexible packaging has been analysed by looking into the different technologies used at the sorting centres as well as technologies used to recycle multilayer films (e.
