h2. Step 6: Numerical Results


h4. Total Deformation

First, examine the total deformation by clicking on the Total Deformation object !Totaldeform.png! in the tree.  Turn on the _Undeformed Wireframe_ as shown below. 
\\
\\ [!beam_def.png|width=350!|^beam_def.png]\\
\\

\\
With 10 line elements, you should see the following output for the total deformation.

\\
If you turn off _View > Thick Shells and Beams_, you will see the deformation of the line elements. The 3D beam view is constructed from this.

The beam deformation can be animated by clicking on the play button, !playbutton.png!, which is located underneath the beam deformation results. This will interpolate between the initial undeformed and final deformed configurations.

h4. Maximum Bending Stress

In order to examine the maximum bending stress first expand the Beam Tool folder, !BeamTool.png!, which is located under "Solution(A6)".  Next, click on the Maximum Bending Stress button, !maxbendstressbutton.png!.  
\\
\\ [!beam_maxbs.png|width=350!|^beam_maxbs.png]\\
\\

Note that in this display, ANSYS shows the same value across the cross-section. This visualization is misleading. The maximum bending stress occurs only at the top fiber. The value that ANSYS reports is 4.635 MPa which matches the value from the [Pre-Analysis|SIMULATION:Cantilever Beam - Pre-Analysis & Start-Up] exactly. 

h3. Bending Moment

To view the bending moment along the beam, click {color:purple}{*}{_}Total Bending Moment{_}{*}{color} in the _Outline_ window. You should see the following in the graphics window.

Also notice that the values were plotted in a graph in the _Graph_ window.

In each of the above, pay close attention to maximum and minimum values of the bending moment. At the wall, the bending moment is 32000 Nm; as the calculation for moment is

{latex}
$
M = F \times d = (8000 N) \times (4 m) = 32000 \mbox{ Nm}
$
{latex}

Which checks out. We also notice that the minimum moment 1.1278E-10 Nm. Because this value is over 1E-14 smaller that the largest value. It can be assumed to be zero. Also, knowing that the calculation for the bending stress is:

{latex}
$
\sigma_M = \frac{M \times y}{I} = 0
$
{latex}

We can have some confidence in our simulation.

h3. Directional Bending Moment

To view the directional bending moment along the beam, click {color:purple}{*}{_}Directional Bending Moment{_}{*}{color} in the _Outline_ window. You should see the following in the graphics window.
