Blanking by means of the finite element method [PDF]

, 1998
This paper summarizes the results of simulating the blanking process by means\ud of the Finite Element Method. Unlike most of the research in this eld, the focus is not on the blanking process itself but on the deformed shape of a product after blanking.

Facets for Art Gallery Problems

, 2013
The Art Gallery Problem (AGP) asks for placing a minimum number of stationary guards in a polygonal region P, such that all points in P are guarded. The problem is known to be NP-hard, and its inherent continuous structure (with both the set of points ...

Statistical approach to determine cutting conditions and cutting geometry for edge trimming of G/PA12 plates

The International Journal of Advanced Manufacturing Technology
Abstract Glass-fibre-reinforced polyamide 12 (G/PA12) composite, a material with considerable potential in the automotive industry, poses notable machining challenges owing to its low glass transition temperature, low matrix stiffness, and the abrasive nature of the glass fibres.

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

Advanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Linear-Time Algorithms for Geometric Graphs with Sublinearly Many Edge Crossings

, 2009
We provide linear-time algorithms for geometric graphs with sublinearly many crossings. That is, we provide algorithms running in O(n) time on connected geometric graphs having n vertices and k crossings, where k is smaller than n by an iterated ...

2D Model of Floor Surface Roughness in Micro Milling Operation [PDF]

International Journal of Advanced Design and Manufacturing Technology, 2010
The micro milling operation is one of the manufacturing processes, which can produce 3D parts in the range of less than a millimetre. Miniaturization of components results in increasing the ratio of surface area to volume of components, which in turn ...

Influence of Tool Wear on the Quality of the Newly Formed Surface in the Drilling of Wood Composites [PDF]

The geometry of a drilling tool largely affects the quality of the newly formed surface. When drilling through a composite panel, the hole edge quality on the outlet side is significantly worse than on the inlet side, so the choice of the appropriate ...

Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires

Advanced Functional Materials, EarlyView.
In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...
