  1. 1. Axially loaded screw joints in wooden structures exposed to fire : Fire tests in furnace and numerical calculations in TASEF of different screw mounting variations

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

    Author : Henrik Pettersson; Emma Wiklund; [2022]
    Keywords : Fire; wood; screw joints; strength; temperature; TASEF; Brand; trä; skruvförband; bärförmåga; temperatur; TASEF;

    Abstract : To achieve sufficient stability of a structure in a fire scenario, a thorough design of joints in wooden structures are as important as the design of the construction itself. As an earlier study points out, there are no existing design method available to determine the load capacity of an axially loaded screw joint in wooden structures, which complicate the process of a thorough design of the joint in a fire scenario.

  5. 4. Chemical analysis for mapping of soot reactivity

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Henrik Pettersson; [2013]
    Keywords : diesel soot; reactivity; oxidation; rail pressure; EGR; TGA; SEM; EDS;

    Abstract : In order to increase the efficiency of diesel particulate filter regeneration more knowledge about diesel soot and its reactivity is required. This thesis compares soot created during accelerated filter loading by lowered rail pressure, with soot from normal filter loading. READ MORE

  6. 5. Reduction of Undesired Range Shifting in an Agricultural Continuously Variable Transmission

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Henrik Knutsson; Michael Pettersson; [2013]
