  1. 1. Characterization of Kelvin Cell Cored Sandwich Structures with Analysis and Experiments

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Sabahattin Bora Günay; [2023]
    Keywords : Kelvin Cell; Sandwich Structure; Space Structures; Three Point Bending Test; Structural Stiffness; Kelvin-cell; smörgåsstruktur; rymdstrukturer; trepunktsböjningstest; strukturell styvhet;

    Abstract : In order to satisfy the mechanical requirements for space structures, achieving lightweight designs is of the greatest significance. The primary focus of this study is the utilization of Kelvin cell core in the design of sandwich structures for space applications. READ MORE

  3. 2. FE-modelling of glulam connection in a pre-tensioned glulam truss : Detailed Finite element modelling of the connection between primary beam and compression stud in a sub-tensioned glulam roof truss

    University essay from KTH/Bro- och stålbyggnad

    Author : Edward Sebastian Swaretz; [2022]
    Keywords : Glulam; sub-tensioned roof truss; connection; instability; Abaqus Standard; Finite element method;

    Abstract : After the collapse of the roof structure in Tarfalahallen 2020, great attention has been focused on instability of sub-tensioned glulam roof trusses. Investigations were launched to find the reason for the collapse and the cause was instability in the roof truss that supported the roof. READ MORE

  4. 3. Parameter study of the diagonal on a gasketed plate heat exchanger

    University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Author : Benjamin Kabil; [2022]
    Keywords : Technology and Engineering;

    Abstract : The aim of this thesis is to further develop the understanding of how different parameters related to the gasket groove of a heat exchanger affect the mechanical performance of the product. Three different parameters with two different gasket materials were evaluated. READ MORE

  5. 4. The impact of mechanical characteristics of GDL on the efficiency of a PEM fuel cell

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Klara Olli; [2022]
    Keywords : Fuel Cell; PEM; gas diffusion layer; bipolar plate; intrusion; Technology and Engineering;

    Abstract : When a fuel cell stack is assembled it is compressed to ensure gas tightness, and as a consequence, the Gas Diffusion Layer (GDL) will intrude into the channels of the Bipolar Plate (BPP). In this work, the GDL is studied in compression tests and through intrusion measurements. READ MORE

  6. 5. Asymmetries in shaped charges

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Gustav Boman; [2021]
    Keywords : ;

    Abstract : This thesis concerns the effects of a select few asymmetries on a jet formingshaped charge. A Shaped charge(SC) is a formed explosive with metal liner thatcollapses under the detonation. The resulting shock­compression results in a jetof metal being shot forward in up 10km/s. READ MORE
