  1. 36. In-plane fracture analysis of paperboard using x-ray tomography

    University essay from Lunds universitet/Hållfasthetslära

    Author : Daniel Andersson; Olof Hedberg; [2018]
    Keywords : paperboard; x-ray tomography; digital volume correlation; dvc; strain field; size effect; tensile experiment; strain rate; Technology and Engineering;

    Abstract : In this Master's Thesis x-ray tomography was used during tensile experiments on paperboard to study delamination and cohesive failure. Digital volume correlation of the x-ray tomograph images enabled quantitative analysis of strain fields. READ MORE

  3. 37. Delamination of Cross-laminated timber and its impact on fire development | Focusing on different types of adhesives

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Eric Johansson; Anton Svenningsson; [2018]
    Keywords : CLT; cross-laminated timber; X-lam; delamination; engineered timber; adhesive; glue; tall timber buildings; timber load-bearing structures; charring rate; NFPA; Paramteric fires; standard testing furnace; Technology and Engineering;

    Abstract : In the recent decade, the interest of building taller all-timber structures using engineered timber materials such as cross-laminated timber (CLT) has increased substantially. On the other hand, there’s also a significant resistance and fear concerning the fire safety of buildings with wood-based load-bearing structures. READ MORE

  4. 38. Development of method for processing brittle-hard materials using Laser Metal Deposition (LMD)

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Alejandro Simó Vesperinas; [2018]
    Keywords : Additive Manufacturing AM ; Laser Metal Deposition LMD ; Direct Metal Deposition DMD ; High-temperature materials; Mo-Si-B alloy; Residual stress; Cracks;

    Abstract : New materials capable of operating at ultra-high temperatures in gas turbine engines are highly desired. Materials such as silicides of refractory metals present great potential to substitute single crystal nickel-based superalloys. READ MORE

  5. 39. Optimization of tear strength in a multi-ply paperboard

    University essay from Karlstads universitet

    Author : Sofie Erhage; [2017]
    Keywords : ;

    Abstract : The thesis has been carried out as a part of the Master of Science in mechanical engineering at Karlstads University. The purpose of the study was to evaluate how different variables affect the tearing resistance in a multi-ply paperboard. READ MORE

  6. 40. Development of Dynamic Test Method and Optimisation of Hybrid Carbon Fibre B-pillar

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Emil Johansson; Markus Lindmark; [2017]
    Keywords : Dynamic test method; B-pillar; Crash worthiness; Side impact crash test; IIHS; Carbon fibre reinforced polymer composite; Composite failure; CFRP; UD; 2x2 Twill; Delamination; Finite Element Method; LS-Dyna; Steel-composite interface; Bilinear fracture toughness;

    Abstract : The strive for lower fuel consumption and downsizing in the automotive industry has led to the use of alternative high performance materials, such as fibre composites. Designing chassis components with composite materials require accurate simulation models in order to capture the behaviour in car crashes. READ MORE
