Additive Manufacturing is revolutionizing the industrial sector for complex and individualized metallic components. The most limiting factor of the widely established laser beam melting technology is the scan velocity due to inertia of the mirrors [1]. In electron beam melting (EBM), ... Read More

Simulation of Thermal Breakdown in a Multi-Layered Stack of Dielectric Elastomers

L. R. Madsen [1], O. Hassager [1], A. L. Skov [1],
[1] Danish Polymer Centre, DTU Chemical Engineering, Lyngby, Denmark

Dielectric elastomers are a promising group of smart materials, which finds application within many fields such as soft robotics, wave-energy harvesting, and loud speakers. A dielectric elastomer consists of a thin, stretchable polymer film sandwiched between two compliant electrodes. ... Read More

Additive Manufacturing of Metal Matrix Composites

F. Wirth [1], K. Wegener [1],
[1] ETH Zurich, Institute of Machine Tools and Manufacturing, Zurich, Switzerland

Laser cladding is an additive manufacturing process, where a laser beam creates a melt pool, into which powder is fed from a powder nozzle. Due to the feed motion of the laser beam and the powder nozzle relative to the workpiece, coatings and 3D parts can be deposited, which consist of ... Read More

A Black-Oil Model for Primary and Secondary Oil-Recovery in Stratified Petroleum Reservoirs

A. Dollari [1], C. Chatzichristos [1], A. Yiotis [1],
[1] National Center for Scientific Research Demokritos, Greece

Black-oil simulators are commonly used in petroleum reservoir engineering for the prediction of oil production, especially during the earlier stages of oil-field exploitation, while also serving to guide pressure maintenance strategies in the longer term. Such models account for fluid ... Read More

Groundwater Flow in the Fractured System Surrounding a Nuclear Waste Repository
