6C. Graph Stresses for a Cross Section of the Plate




MAIN MENU ->
General Postproc

      GENERAL POSTPROC ->
Path Operations

            
PATH OPERATIONS ->
Define Path-By Nodes

                                                 

 

 

For the ByNodes window, pick two points along
the right side of the rectangle, which are (4,0) and (4,2).


The order of points you pick matters in the plot across the section. The first point you choose will have the coordinate of
zero in the graph while the other point will be located at 2.

Then click OK.

In the "Define Path Name" box, type: 1,



In the Define Path Name box, type 1.

Click OK. Then you will see the PATH command window. Close the window.

PATH OPERATIONS -> Map Onto Path

Stress in X direction

In the window MAP RESULTS ITEMS ONTO PATH , click on Stress and X-Direction SX or whichever stress component is relevant.

Then click OK. Now you have specified the path which you want to generate a solution along. Then, make a call to the function that plots the graph for us.

GENERAL POSTPROC --> Path Operations

PATH OPERATIONS -> Plot Path Items

PLOT PATH ITEMS -> On Graph

In the PATH PLOT OF PATH ITEMS window, highlight SX.

Click OK.

Then a graph of stress component along the chosen path will appear as shown in the figure below.

(add figure 6c8)

Stress in Y direction

You can also get plots of Sigma yy vs. y
at x=4 by following steps similar to those listed above.
Once this is done you can compare the data to the values you expect from elementary theory of an axially-loaded member.

Go back to the Map Onto Path command.

PATH OPERATIONS -> Map Onto Path

In the window MAP RESULTS ITEMS ONTO PATH , click on Stress and Y-Direction SY.

PLOT PATH ITEMS -> On Graph

In the PATH PLOT OF PATH ITEMS window, highlight SY.

You should be able to get the figure below.

If you cannot see the picture, remember to go to replot command in the menu bar.

<-------- Sigma yy

Note: The stress in Y direction is approximately zero. In different versions of ANSYS, this graph differs bacause of different algorithms each version uses in solving.


Shear Stress XY

You can also get plots of Shear Stress xy vs. y at x=4 by following steps similar to those listed above.
Once this is done you can compare the data to the values you expect from elementary theory of an axially-loaded member.

Go back to the Map Onto Path command.

PATH OPERATIONS -> Map Onto Path

In the window MAP RESULTS ITEMS ONTO PATH , click on Stress and SY-Shear SXY.

PLOT PATH ITEMS -> On Graph

In the PATH PLOT OF PATH ITEMS window, highlight SXY.

You should be able to get the figure below.

If you cannot see the picture, remember to go to replot command in the menu bar.

<-------- Tau xy

 

Note: The stress in Y direction is approximately zero.
