  1. 31. PICASSO UNDER INVESTIGATION Condition Assessment of the Acrobat Family by Pablo Picass

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Eleonora Papa; [2018-05-07]
    Keywords : Pablo Picasso; cardboard; optical microscopy; multispectral imaging; fiber analysis;

    Abstract : This study focuses on a painting on cardboard by Pablo Picasso (1881-1973), The Acrobat Family, created in 1905 and currently part of the collection of the Gothenburg Museum of Art. Because of the scarcity of documentation about the object's condition, the necessity of an extensive investigation has arisen on the occasion of a loan request from abroad. READ MORE

  3. 32. 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. 33. 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. 34. 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.

  6. 35. Simulation of Delamination Migration in Laminated Composite Structures - An Approach Combining Extended Finite Elements and a Cohesive Zone Model

    University essay from Lunds universitet/Hållfasthetslära

    Author : Viktor Björklund; [2018]
    Keywords : Crack propagation modeling; Fiber-reinforced polymer; Laminated composites; FRP; CFRP; Cohesive zone model; CZM; Delamination migration; FEM; XFEM; Fracture mechanics; Progressive damage modeling; Surface-based cohesive behaviour; Technology and Engineering;

    Abstract : Fiber-reinforced polymer matrix composites are being used increasingly in lightweight applications where high strength and stiffness is required. One of the main challenges with designing components from such materials is to predict the ultimate strength and behaviour of the structure. READ MORE
