It is expected that the present research work will be highly useful for understanding the dynamic effects during sinter-forging of complicate shape preforms, e.g. irregular polygonal shape.
The complicate shape of the CSS allows the ports to pass through the structure and reach their place into the vacuum vessel.
Tracking data may be sparse and not particularly accurate, the objects' complicate shape and unknown attitude evolution may render difficult the aerodynamic computations and, last but not the least, the models used to predict the air density at the altitudes of interest, as a function of solar and geomagnetic activity, are affected by significant uncertainties.
Some of these are very intricate, with negative space or complicated shapes.
Building a machine's components a layer at a time means that complicated shapes can be made more easily than by starting with a lump of metal and removing what is not needed.
The method yields very accurate results even for surfaces with singularities, concavities, complicated shapes or nonzero genus.
The dish (not pictured), which consists of large loops of tangled noodles the researchers call anelloni (from the Italian word for "ring"), is an effort to show how ringlike polymers can form complicated shapes, Physics World reports.
Subtractive manufacturing, the traditional machining technique has the disadvantage in that it is difficult to make complicated shapes by computer numerical control (CNC) milling and there is a lot of material waste [14].
As a result of the completed analysis the critical values of the characteristic parameters are found, and it is shown that the modes of incipient buckling possess complicated shapes associated with the tube spiral curving prevailing in the zone of bottom-hole-assembly.
All these results indicated that the high PCL content was unfavorable for 3-D cartilage regeneration, especially for the cartilage with a complicated shape, and that GT/PCL 70 30 might be a relatively suitable ratio for ear-shaped cartilage regeneration.
