TIP: You should start ABAQUS CAE via command line from the directory you want your results files to end up.
Example: Let’s look at a 3D beam that has dimensions of 200mm length, 20 mm height, and 30 mm width. The width dimension was extruded. We want to change this to an extrusion of 10 mm.
You can adjust a parts geometry by adjusting a dimension. Let’s use the beam example to show how this can be done. Let’s say the beam must be shortened to 100 mm. Because this is not an extruded dimension we must adjust this using dimensions.
This button is called Create Dimension Horizontal
Now that we have a dimension we can adjust the length of the beam by changing the number in the dimension.
6. Click on the button called Edit Dimension Value
7. Click on the dimension number that will be changed then hold down the Shift key and click on the end points of one of the vertical lines.
8. When you are done click the middle mouse button (the wheel). It will prompt you for the new dimension. Enter 100 then OK.
Your sketch will look like
When you click Done the 3D view will redraw itself to look like
There may be times where you would like to add an extrusion to an existing part. Sort of like growing an additional geometry on an existing geometry.
For this example we want to add a small cantilever extension along the current longitudinal axis of the existing beam. The dimensions of this extrusion is 50mm long, 5mm high and 10mm wide.
6. In the dialog box make sure Type is Blind and Depth is 50. When you click ok the beam now looks like.
To obtain more insight into the stresses and strains of a loaded structure we may want to view results along a line rather than a point.
To demonstrate this we will use the example of the 3D cantilever beam. In this example we want to see the stresses along a centered vertical line just inside the structure at the root.
In using the Display Group functionality spoken of in a previous lecture we will display just those elements at the root end.
Now we would like to tell ABAQUS we want to view the results along the vertical centerline of the displayed elements. We do this by defining a path.
There are two ways to define a path 1) using node numbers and 2) by specifying points.
If you use nodes the nodes will displace when the structure is loaded.
In our example we will use nodes.
