    Sammanfattning : Based on a participatory action research methodology and approach (AR), this dissertation explores the core theoretical problems and opportunities of education and learning for sustainable development (ESD) within the cross-disciplinary area of integrated and sustainable conservation of built environments. The main purpose has been to develop an epistemological framework for integrated lifelong learning, ethics and advanced research (R&D) and to provide a new sustainable education and career model for the field to be applied in the Dalecarlia region and on a national level within the Swedish construction industry at large; i.

  5. 4. Laser powder bed fusion of 316L stainless steel - Microstructure and mechanical properties as a function of process parameters, design and productivity

    Författare :Alexander Leicht; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tensile properties; productivity; design for additive manufacturing; additive manufacturing; thin-wall structures; stainless steel; laser powder bed fusion; microstructure; 316L;

    Sammanfattning : One of the most common additive manufacturing techniques for fabricating metallic components is laser powder bed fusion, which has demonstrated great potential in fabricating parts with properties exceeding the properties achieved via conventional methods. To fully utilize the process’s potential, a more profound understanding of the microstructure and properties of the laser powder bed fusion processed material is required. LÄS MER

  7. 5. A design-build contractor risk assessment framework for new technical solutions in the construction industry

    Författare :Charlotte Svensson Tengberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture safety; Hygrothermal performance; risk assessment; Design–build contractor; Serial failure; New technical solutions;

    Sammanfattning : Design–build contractors are often challenged to introduce new technical solutions into construction projects. However, they might not have methods and resources required to avoid serial failure, which is defined as multiple cases of failure when a technical solution fails to sustain the performance requirements.
