  1. 21. Experimental analysis of limitations in the strut-and-tie method

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Mikael Wahlgren; Niels Bailleul; [2016]
    Keywords : Strut-and-Tie method; Reinforced concrete; Concrete Damaged Plasticity; Fracture energy; Technology and Engineering;

    Abstract : One of the overall main purposes for a structural engineer is to design structures and structural elements so that they meet society’s safety requirements, yet use as little material as possible. In order to do so, the designer has to understand and simplify a complex reality. READ MORE

  3. 22. Fracture Simulation of Electrofusion Joining.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Amir Alizadeh; [2015]
    Keywords : ;

    Abstract : This Master thesis investigates mechanical failures of electrofusion joints. This type of joints are used for weld high density polyethylene pipe systems where tting and pipe will be welded together by the heat caused by the resistance of the copper cables to electric current.

  4. 23. DEVELOPMENT OF A MODEL OF THE DEGRADATION OF THE MECHANICAL PROPERTIES OF POLYOXYMETHYLENE (POM) IN THE PRESENCE OF BIODIESEL

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Adriano Linero Jiménez; [2014]
    Keywords : Aging; Polyoxymethylene; Diffusion; Biodiesel;

    Abstract : This project analyses the impact in the mechanical properties of Polyoxymethylene (POM) of three different blends of biodiesels: B0 with 0% of Rapeseed Methyl-ester (RME), B20 with 20% of RME and B100 with 100% of RME. Polyoxymethylene specimens have been subjected to an accelerated aging during 1600 hours at 85ºC. READ MORE

  5. 24. Mechanical properties dependence on microstructure in aerogel-like Quartzene®

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Alexander Ekström; Olof Gustafsson; Anders Kvarned; Elinor Löf-Nilsson; Sebastian Proper; Markus Sköld; Pär Snögren; Oscar Ullsten; [2014]
    Keywords : aerogel; pore size; crush-test; mechanical properties; Quartzene; density; microstructure; fracture;

    Abstract : In this project the relation between pore size/porosity and the mechanical properties has been studied in the aerogel-like material Quartzene®. Quartzene® is a patented material produced by Svenska Aerogel AB. Density measurements were made on three different types of Svenska Aerogels ABs Quartzene® in the shape of pellets. READ MORE

  6. 25. Numerical modelling of deformation within accretionary prisms

    University essay from Institutionen för informationsteknologi

    Author : Ting Zhang; [2012]
    Keywords : Discrete Element Method; accretionary wedge; basal friction; compression force; area loss; displacement;

    Abstract : A two dimensional continuous numerical model based on Discrete Element Method is used to investigate the behaviour of accretionary wedges with different basal frictions. The models are based on elastic-plastic, brittle material and computational granular dynamics, and several characteristics of the influence of the basal friction are analysed. READ MORE
