  2. 11. Towards Virtual Tryout and Digital Twins : Enhanced Modeling of Elastic Dies, Sheet Materials, and Friction in Sheet Metal Forming

    Author : Johan Pilthammar; Sharon Kao-Walter; Mats Sigvant; Wolfram Volk; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sheet Metal Forming; Stamping Die; Virtual Tryout; Digital Twin; Stamping Press; Structural Analysis; Finite Element Simulation; Optimization; Digital Image Correlation; Inverse Modeling; Maskinteknik; Mechanical Engineering;

    Abstract : Competition and complexity in the global car market are continuously increasing. To gain an edge in the market while making a profit, each competitor in the market needs a strong focus on technology development. Such a focus will increase the value of the product for the customers. READ MORE

  4. 12. Foam-formed Fiber Networks: Manufacturing, Characterization, and Numerical Modeling : With a Note on the Orientation Behavior of Rod-like Particles in Newtonian Fluids

    Author : Majid Alimadadi; Per Gradin; Pär Jonsén; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D fiber network structure; foam forming; numerical modeling; compression simulation; orientation; wall-bounded flow; CFD; Jeffery orbits; LS-DYNA;

    Abstract : Fiber networks are ubiquitous and are seen in both industrial materials (paper and nonwovens) and biological materials (plant cells and animal tissues). Nature intricately manipulates these network structures by varying their density, aggregation, and fiber orientation to create a variety of functionalities. READ MORE

  5. 13. Modeling and Diagnosis of Friction and Wear in Industrial Robots

    Author : André Carvalho Bittencourt; Svante Gunnarsson; Mikael Norrlöf; Andrew Starr; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : High availability and low operational costs are critical for industrial systems. While industrial equipments are designed to endure several years of uninterrupted operation, their behavior and performance will eventually deteriorate over time. READ MORE

  6. 14. Computational modeling of hot rolling

    Author : Jonas Edberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Aided Design; Datorstödd maskinkonstruktion; Material Mechanics; Materialmekanik;

    Abstract : This thesis consists of six papers on finite element simulations of the hot rolling of plates. Different friction and material models have been evaluated. The work includes both numerical simulation and experimental verification. READ MORE

  7. 15. Understanding Adhesive Mixtures for Inhalation : Particle Dynamics Modelling and Segregation Experiments

    Author : Sohan Sarangi; Göran Frenning; Göran Alderborn; Kyrre Thalberg; Johannes Khinast; Uppsala universitet; []
