  2. 1. Continuum modeling of paperboard for the mechanical response of converting processes

    Author : Kristofer Robertsson; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paperboard; Continuum modeling; Converting processes; FEM simulations; Finite strain theory; Damage modeling; Rate-dependent; Creasing and folding; Out-of-plane experiments;

    Abstract : Paperboard is a thin and lightweight material made of cellulose fibers and it is an important component in packaging material where it provides stiffness and rigidity. The scope of this work is the development of continuum models, and its numerical treatments, for simulating the processes of converting paperboard into packages. READ MORE

  4. 2. Numerical and Experimental Investigation on Paperboard Converting Processes

    Author : Hui Huang; Mikael Nygårds; Ron Peerlings; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : An investigation of the mechanical properties of paperboard and its influence on converting processessuch as creasing, folding and forming, from both an experimental and numerical perspective wasperformed. Fundamental research to establish a material model for paperboard, and an experimentalout-of-plane shear test method was suggested. READ MORE

  5. 3. Converting CAD Drawings to Product Models

    Author : Robert Noack; KTH; []
    Keywords : Shape recognition; shape interpretation; product models;

    Abstract : The fundamental aim of this study is to examine whether itis possible to automatically convert vector-based drawings toproduct models. The reason fordoing this is that the newobject-based systems cannot make use of the information storedin CAD drawings, which limits the usability of thesesystems. READ MORE

  6. 4. Limiting processes in anion-exchange membrane fuel cells

    Author : Henrik Grimler; Göran Lindbergh; Rakel Wreland Lindström; Carina Lagergren; Marc Secanell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anion-exchange membrane fuel cell; hydrogen oxidation reaction; oxygen reduction reaction; water transport; physics-based modelling; Chemical Engineering; Kemiteknik;

    Abstract : Fuel cells allow for converting chemical energy stored in hydrogen into electrical energy, with only heat and water as by-products. In a sustainable energy society, hydrogen may play an important role due to its ability to act both as an energy carrier and as a valuable chemical in the process industry. READ MORE

  7. 5. Development of biocatalytic processes for selective antioxidant production

    Author : Io Antonopoulou; Paul Christakopoulos; Ulrika Rova; Evangelos Topakas; Anne S. Meyer; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Abstract : Feruloyl esterases (FAEs, EC 3.1.1.73) represent a subclass of carboxylic acid esterases that under normal conditions catalyze the hydrolysis of the ester bond between hydroxycinnamic acids (ferulic acid, sinapic acid, caffeic acid, p-coumaric acid) and sugar residues in plant cell walls.
