  1. 21. 3D Finite Element Modeling of the Lower Limb

    University essay from Högskolan i Jönköping/JTH, Produktutveckling

    Author : Zhao Xuefang; [2016]
    Keywords : ;

    Abstract : This thesis project provides a method to simulate the internal mechanical properties of the undeformed human lower limb when an external force is applied. The value of the external force is determined by the deformed magnetic resonance imaging (MRI) images, which is converted into displacement instead. READ MORE

  3. 22. Structural analysis of thermal interface materials and printed circuit boards in telecom units - a methodology

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

    Author : Mattias Good; [2016]
    Keywords : hyperelastic; viscoelastic; fem; finite element method; telecom; cooling; solid mechanics; nonlinear; uniaxial compression; printed circuit board; pcb; polymer; rubberlike; filled silicone rubber; gappad; thermal pad; mullins effect; cyclic loading; stress softening;

    Abstract : En struktur analys på Ericssons MINILINK-6352 har utförts för att undersöka spänningar och deformationer på enheten, främst med fokus på de termiska gränskiktsmaterialen och buktningar av kretskortet. Dessa är viktiga aspekter när man överväger om enheten är termiska lämpad ur en mekanisk synvinkel, där god ytkontakt mellan de olika kropparna är avgörande för ordentlig kylning genom värmeledning.

  4. 23. Design of slender steel members : A comparison between the reduced stress method and the effective width method

    University essay from KTH/Bro- och stålbyggnad

    Author : Oskar Skoglund; Daniel Samvin; [2016]
    Keywords : Steel structures; finite element method; reduced stress method; effective width method; nonlinear finite element method; Stålkonstruktion; finita element metoden; reducerad spänningsmetoden; effektiva bredd metoden; olinjär finita element analys;

    Abstract : As of now, the most common way in Sweden, to address the issue of local buckling of steelstructures is through the procedure called the effective width method. A less commonprocedure for dealing with local buckling is the reduced stress method. READ MORE

  5. 24. Second-order FE Analysis of Axial Loaded Concrete Members According to Eurocode 2

    University essay from KTH/Betongbyggnad

    Author : Nessa Yosef Nezhad Arya; [2015]
    Keywords : Second-order; nonlinear; slender reinforced concrete column; ABAQUS; FE analysis; curvature method; nominal stiffness method; eccentrically loaded; benchmark experiment; parametric study; Andra ordningens effekt; icke-linjär; slank armerad betongpelare; ABAQUS; FE-modellering; krökningsmetoden; styvhetsmetoden; excentrisk last; utvärderingsförsök; parameterstudie;

    Abstract : A nonlinear finite element analysis was performed for an axial loaded reinforced concrete column subjected to biaxial bending taking into account second-order effects. According to Eurocode there are two ways to take second-order effects into consideration: nonlinear FE analysis and hand calculation based on the simplified methods explained in Eurocode 2.

  6. 25. Comparison of ASTM and BSI Standards for the calculation of fracture energy of adhesives : Design of a fixture and testing of DCB specimens

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap; Högskolan i Skövde/Institutionen för informationsteknologi

    Author : Francisco Manuel Rodríguez Moronta; Judith Segurola Lucas; [2015]
    Keywords : DCB; standards; adhesives; fracture energy;

    Abstract : Modern synthetic structural adhesives are finding a place in the drive to improve the fuel efficiencyof automobiles through weight reduction of the structure. One of the most important properties ofthe adhesives used in this type of joining is the fracture energy. READ MORE
