Tutorial - 2D Truss analysis in Mechanical APDL (ANSYS) Part 2?

In general, a finite element solution may be broken into the following three stages.
1. Preprocessing: defining the problem;
- Define keypoints/lines/areas/volumes
- Define element type and material/geometric properties
- Mesh lines/areas/volumes as required
2. Solution: assigning loads, constraints and solving;
3. Postprocessing:
- Lists of nodal displacements
- Element forces and moments
- Deflection plots
- Stress contour diagrams
In this tutorial we will go through second and third step.
-
Step 1:
This is the second part of tutorials in Which we solve the problem. Under Solution >> Analaysis Type >> New analysis. Select static and click OK.
-
Step 2:
Under Define Loads >> Apply >> Structural >> Displacement >> On keypoints. We will now define the fixed keypoints or supports.
-
Step 3:
Select the two lower corner keypoints and click OK.
-
Step 4:
Select All DOF and click OK.
-
Step 5:
Goto Define loads >> Apply >> Structural >> Force/Moment >> On Keypoints.
-
Step 6:
Select the upper keypoints and click OK.
-
Step 7:
Direction of force be FY and input Force value = -10000 since the force will be acting downward.
-
Step 8:
Now we have the model prepared for solution. Under Solve >> Current Load step.
-
Step 9:
Click OK.
-
Step 10:
A message Solution is done! will show when the process is completed. Click Close.
-
Step 11:
Now the third part of this process. Post-Processing is to be done. Goto General PostProc >> List Results >> Reaction Solu.
-
Step 12:
Select all items and click OK.
-
Step 13:
Now we have the value of reaction about the node 1 and 5 which are fixed. Click Close.
-
Step 14:
Goto Plot Results >> Deformed shape.
-
Step 15:
Select Def + undeformed. Click OK
-
Step 16:
Now we have the deformation plot.
-
Step 17:
Goto Plot results >> Contour plot >> Nodal Solu.
-
Step 18:
Under Stress select von Mises stress and click OK.
-
Step 19:
We have von Mises stress plot.
