In Atanasiu (1980), the plug tube drawing process (Figure 15.8b) was considered. Again using a viscoplastic material model, but allowing for change in yield stress as a function of ultrasonic intensity, results showed a significant reduction of draw force for all die angles, with an optimum ...
The new simulation of the plastic deformation in the dies also indicated optimum semi-die angles away from the traditional eight degrees.

To illustrate, here’s code to draw our arrow repeatedly at several angles, pivoting around the end of its tail (Figure 15.16). First, we’ll encapsulate the drawing of the arrow as a UIImage. Then we simply draw that UIImage repeatedly: UIGraphicsBeginImageContextWithOptions(CGSizeMake(40...
wherein the dihedral angles are located by the steps as follows: from a zero point, clockwise locating the bends connected among the straight pipes into the negative dihedral angle, counterclockwise locating the bends connected among the straight pipes into the positive dihedral angle; and arranging...
It has four equal sides and four right angles, so that's a square.So, that makes six squares altogether.Four 1 by 1 squares, one 2 by 2 square and one x by x square.What is the value of x? We can use Pythagoras' Theorem to find it: x2 = 12 + 12 = 1 + 1 = 2 So x...
These include automated note and highlighting systems, as well as tools to indicate the lengths, sizes, and angles of the object outlines, or the distance between nominated objects. An example of an annotated layout drawing view A callout associated with a connector or a connection point and ...
Recent cognitive experiments have shown that the negative impact of an edge crossing on the human understanding of a graph drawing, tends to be eliminated in the case where the crossing angles are greater than 70 degrees. This motivated the study of RAC
This applies to member details and submaterial details. On member details, this is the total length of the member main material. Example: For a beam with clip angles on both ends, this distance is measured from the ends of the beam, not from the faces of the clip angles. Report ...
The mouse is a convenient pointer controller for selecting options on screen and drawing graphics. The original mouse used two rollers set at right angles, with perforated disks attached. The holes were detected using an opto-sensor, sending pulses representing movement in two directions to the CPU...
After adding Drawing Tools to a view, they can be easily formatted, moved, re-sized, deleted, hidden or copied. To edit drawing tools, you can use the options in the Tools menu, or a variety of shortcuts: If youleft-clickon a drawing tool, you can re-size or move the tool by cl...
