  2. 1. Residual Stress Distributions in Additively Manufactured Parts : Effect of Build Orientation

    Author : Prabhat Pant; Ru Lin Peng; Johan Moverare; Kjell Simonsson; Jonathan Almer; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Residual stress; Neutron diffraction; FEM;

    Abstract : Additive manufacturing (AM) of parts using a layer by layer approach has seen a rapid increase in application for production of net shape or near-net shape complex parts, especially in the field of aerospace, automotive, etc. Due to the superiority of manufacturing complex shapes with ease in comparison to the conventional methods, interest in these kinds of processes has increased.

  4. 2. Increased Productivity of Ferrous Alloys Produced by Powder Bed Fusion - Laser Beam

    Author : Rasmus Gunnerek; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; additive manufacturing; process optimization; build rate; build speed; powder bed fusion – laser beam; porosity; low alloy steel; 316L stainless steel; productivity in AM;

    Abstract : Low production speeds limit wider adoption of powder bed fusion – laser beam (PBF-LB) in cost sensitive industries as it correlates directly with high production costs. The main process parameters such as scan speed, hatch distance and layer thickness can be scaled up to increase build speed, but it often comes at a trade off in lower quality, i. READ MORE

  5. 3. Integrated Design-Build Management - Studying Institutional Processes to Understand Project Coordination & Performance

    Author : Lea Urup; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; coordination; institutional work; and; project performance.; design-build;

    Abstract : An increasing number of actors contributing with their skills to design-build projects increase the need for and complexity of coordination. The design-build project delivery method proposes to coordinate actors through collaborative interaction; however, even design-build projects result in poor coordination and building of relatively poor quality.

  6. 4. Improving productivity in design and construction of bridges

    Author : Johan Lagerkvist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design Bid-Build; Design-Build; Productivity; Lean Construction; Bridge design; Standardisation; Early Contractor Involvement; Bridge construction;

    Abstract : Building new infrastructure is an essential part of developing society. The construction industry is also an important part of economic growth, accounting for 13% of the world's GDP. At the same time, the construction industry lacks behind in increasing its productivity. READ MORE

  7. 5. An indirect route to equality : taxing consumers to build the Swedish welfare state

    Author : Gunnar Lantz; Thomas Pettersson; Lena Andersson-Skog; Svante Prado; Umeå universitet; []
