  1. 1. Phase Change Material : Potential for increased fire resistance in concrete

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : William Toivanen; [2023]
    Keywords : Phase change material; concrete; fire resistance; integration into building materials; latent heat; melting;

    Abstract : The European commission has in the Energy Performance of Buildings Directive from 2010 decided that its member states were required to ensure that all new buildings by the end of 2020 were nearly zero-energy buildings. These buildings require small amounts of energy compared to its performance in example by keeping a pleasant indoor climate. READ MORE

  3. 2. Synergistic fire- and mechanical effect of biochar and ammonium polyphosphate in epoxy composite

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Anton Olausson; Ludvig Jönsson; [2023]
    Keywords : Ammonium polyphosphate; Biochar; Composite; Epoxy; Synergistic effect;

    Abstract : Polymer composites are used in a varying extent and are challenging the use of traditional materials due to the push towards sustainable development. They have replaced steels and aluminum alloys in applications. READ MORE

  4. 3. Punching shear in concrete flat slabs supported on slender edge steel columns

    University essay from KTH/Betongbyggnad

    Author : Pasha Jalal; Jose Andres Perez; [2020]
    Keywords : Punching shear; ATENA; FEA; precast slab; flat slab; top and foot plate.; Genomstansning; ATENA; FEA; plattbärlag; pelardäck; topp- och fotplåt.;

    Abstract : Punching shear is a failure mechanism caused by concentrated loads, creating a crack pattern that resembles a cone shape or piece of pie starting from the top surface of the slab and prolongs downwards. When the total shear force is greater than the shear resistance of the slab, it may eventually lead to punching shear failure. READ MORE

  5. 4. Resistance Spot Welding of AlSi-coated Ultra High Strength Steel : An experimental study

    University essay from KTH/Materialvetenskap

    Author : Kristofer Hjelmtorp; [2019]
    Keywords : RSW; resistance spot welding; usibor; boron steel;

    Abstract : The automotive industry of today faces ever harder requirements from regulatory bodies to increase the fuel efficiency, reduce the carbon footprint and increase the safety of their vehicles. The problem is being tackled in different ways; one of them being the use of innovative materials to reduce the overall weight while improving the crash safety of the vehicle. READ MORE

  6. 5. Endeavors toward Novel Cochlear Implants from Stretchable Printed Circuit Board Technology

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Rickard Viik; [2019]
    Keywords : novel; cochlear; implant; electrode array; electrode; stretchable; soft; electronics; pdms; polydimethylsiloxane; liquid; alloy; galinstan; hearing aid;

    Abstract : Profound sensorineural hearing loss is at the present time a major worldwide health concern, affecting over 5% of the worlds' population. Through cochlear implants (CI), treatment of sensorineural hearing loss now offers the possibility to restore hearing function through electrical stimulation of auditory nerves. READ MORE
