  2. 1. In conversation with simulation: The application of numerical simulation to the design of structural nodal connections

    Author : Jens Olsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; 3D Printing; Design theory; Structural design; Structural efficiency; Simulation; Peridynamics; Force flux density; Nodal connections; Conceptual design; Steel structures; Design process; Digital design;

    Abstract : The thesis explores methods for integration of structural analysis, design and production in a digital design environment. The somewhat ambiguous title implies the ambition to make such integration in relation to the explorative phase of the design process which is described by Donald Schön as having a conversational character.

  4. 2. Advancing the life cycle energy optimisation methodology

    Author : Hamza Bouchouireb; Ciarán J. O'Reilly; Peter Göransson; Rupert J. Baumgartner; José Potting; Tracy Bhamra; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; life cycle energy; vehicle design; optimisation; functional conflicts; livscykelenergi; fordonsdesign; optimering; tvär-funktionella konflikter; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : The Life Cycle Energy Optimisation (LCEO) methodology aims at finding a design solution that uses a minimum amount of cumulative energy demand over the different phases of the vehicle's life cycle, while complying with a set of functional constraints. This effectively balances trade-offs, and therewith avoids sub-optimal shifting between the energy demand for the cradle-to-production of materials, operation of the vehicle, and end-of-life phases.

    Abstract : The transition from conventional cast concrete to 3D Concrete Printing (3DCP) marks a paradigm shift by directly depositing fresh concrete layer upon layer according to a digital model without the need for a formwork. This technology offers the possibility of achieving innovative and complex geometries in an automated process. READ MORE

  6. 4. Robust design : Accounting for uncertainties in engineering

    Author : David Lönn; Larsgunnar Nilsson; Niclas Strömberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robust optimisation; robust design; robustness; meta model; sensitivity analysis; Solid mechanics; Fastkroppsmekanik;

    Abstract : This thesis concerns optimization of structures considering various uncertainties. The overall objective is to find methods to create solutions that are optimal both in the sense of handling the typical load case and minimising the variability of the response, i.e. robust optimal designs.

  7. 5. Life Cycle Energy Optimisation: A multidisciplinary engineering design optimisation framework for sustainable vehicle development

    Author : Hamza Bouchouireb; Ciarán J. O'Reilly; Peter Göransson; Rupert J. Baumgartner; José Potting; Mario Hirz; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life cycle energy optimisation; Multidisciplinary optimisation; Integrative design; Sustainable vehicle design; Functional conflicts; Vehicle aerodynamics; Battery energy storage systems; Robust design; Uncertainty propagation; Livscykelenergi; Fordonsdesign; Optimering; Tvär-funktionella konflikter; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : This thesis explores how the systemic-level environmental footprint of light-duty vehicles could be reduced through integrative design using the Life Cycle Energy Optimisation (LCEO) methodology. This methodology aims at finding a design solution that uses a minimum amount of cumulative energy demand over the different phases of the vehicle's life cycle; while complying with a set of functional constraints, thereby avoiding any sub-optimal energy demand shifts between the vehicle's different life cycle phases.
