  2. 16. Computational modelling of structural battery composites

    Author : David Carlstedt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Element Analysis FEA ; Multifunctional materials; Carbon fibre composites; Thermo-electro-chemo-mechanical coupling; Li-ion batteries;

    Abstract : Batteries and surrounding structures (e.g. battery modules and packs) in electrical vehicles and devices are often designed in a way that prevents the electro-chemically active part of the battery cells from being exposed to mechanical loads during operation/service. READ MORE

  4. 17. Cost/Weight Optimization of Aircraft Structures

    Author : Markus Kaufmann; Dan Zenkert; Frédéric Lani; KTH; []
    Keywords : Cost Weight Optimization; Weight Penalty; Direct Operating Cost; Composite Structures; Non-destructive testing; Finite element analysis FEA ; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Composite structures can lower the weight of an airliner significantly. The increased production cost, however, requires the application of cost-effective design strategies. Hence, a comparative value is required which is used for the evaluation of a design solution in terms of cost and weight. READ MORE

  6. 19. On cyclic accumulation models for degradation of railway foundations

    Author : Hossein Tahershamsi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural soft clay; Global Sensitivity Analysis; Sobol method; Experimental design; Rate-dependent models; Cyclic accumulation models; Cyclic degradation; Uncertainty analysis;

    Abstract : The degradation of railway foundations due to the repeated loading of traffic induces maintenance and safety obligations for the track operator. One major contributor to track degradation is the accelerated settlement rates in soft soils below the track that lead to alignment issues, especially at stiffness transitions. READ MORE

  7. 20. Holistic Assessment of Survival Time after Ship Collision

    Author : Per Hogström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear FEA; failure modelling; ship collision; sheet metal failure; uncertainty analysis; Damage stability;

    Abstract : Collisions between ships contribute to ship losses even in modern time, and the International Maritime Organization (IMO) strives towards a more risk-based view on addressing the damage stability of ships. This thesis presents a holistic methodology for computing the consequences of ship collisions. READ MORE
