2. 1. Accelerated granular matter simulation

   Author : Da Wang; Martin Servin; Jin Ooi; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; discrete element method; nonsmooth contact dynamics; multibody dynamics; granular media; simulation; projected Gauss-Seidel; validation; iron ore pellets; pelletising balling circuit; model reduction; design optimization;

   Abstract : Modeling and simulation of granular matter has important applications in both natural science and industry. One widely used method is the discrete element method (DEM). It can be used for simulating granular matter in the gaseous, liquid as well as solid regime whereas alternative methods are in general applicable to only one. READ MORE

4. 2. Shear Fracture and Delamination in Packaging Materials : A study of Experimental Methods and Simulation Techniques

   Author : Md. Shafiqul Islam; Sharon Kao-Walter; Christian Johansson; Johan Tryding; Blekinge Institute of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Package opening; Shear test specimen; Stress intensity factor; Finite Element simulation; Scanning electron microscopy; Polymers; Interlaminar shear delamination;

   Abstract : Packages are the means of preservation, distribution and convenience of use for food, medicine and other consumer products. Package opening is becoming complicated in many cases because of cutting cost in design and production of opening techniques. READ MORE

5. 3. Plasticization of Biobased Polymers: A Combined Experimental and Simulation Approach

   Author : Hüsamettin Deniz Özeren; Mikael S. Hedenqvist; Richard Olsson; Fritjof Nilsson; Kim Bolton; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; plasticization; starch; gluten; simulation; molecular dynamics; glycerol; mjukgörning; stärkelse; gluten; simulering; molekyldynamik; glycerol; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : The field of bio-based plastics has developed significantly in recent decades and there is an increasing demand for industries to shift from petrochemical to biobased polymers. Biobased polymers offer competitive properties, and in many cases have advantages in terms of cost. READ MORE

6. 4. At the Mountains of Modeling : Multiscale Simulations of Desalination by Capacitive Deionization

   Author : Johan Nordstrand; Joydeep Dutta; Oscar Tjernberg; Maarten Biesheuvel; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Capacitive Deionization; Desalination; Modeling; Multiscale; Simulation; Avsaltning; Kapacitiv Avjonisering; Modellering; Multiskala; Simulering; Material and Nano Physics; Material- och nanofysik; Physics; Fysik;

   Abstract : More than 2 billion people are living in water-scarce areas. Meanwhile, there are enormous amounts of water in the salty oceans. Capacitive deionization (CDI) rises to the challenge with electrochemical cells for desalinating the water. As the CDI field expands, modeling becomes an increasingly important part of the development landscape. READ MORE

7. 5. Simulation of Microstructure-based Mechanical Behaviour of Cast Components

   Author : Jakob Olofsson; Ingvar L. Svensson; Salem Seifeddine; Franco Bonollo; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Component behaviour; structural analysis; mechanical behaviour; casting process simulation; Finite Element Method FEM simulation;

   Abstract : In the process of developing cast iron and cast aluminium components, a high level of co-operation between product development and production is of great importance. From an engineering standpoint, this co-operation is limited early in the product development phase by e.g. READ MORE
