Tutorial on two dimensional bridge truss analysis in ANSYS 13.0.
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;
- Lists of nodal displacements
- Element forces and moments
- Deflection plots
- Stress contour diagrams
In this tutorial we will go through second and third step.
This is the second part of tutorials in Which we solve the problem. Under Solution >> Analaysis Type >> New analysis. Select static and click OK.
Under Define Loads >> Apply >> Structural >> Displacement >> On keypoints. We will now define the fixed keypoints or supports.
Select the two lower corner keypoints and click OK.
Select All DOF and click OK.
Goto Define loads >> Apply >> Structural >> Force/Moment >> On Keypoints.
Select the upper keypoints and click OK.
Direction of force be FY and input Force value = -10000 since the force will be acting downward.
Now we have the model prepared for solution. Under Solve >> Current Load step.
A message Solution is done! will show when the process is completed. Click Close.
Now the third part of this process. Post-Processing is to be done. Goto General PostProc >> List Results >> Reaction Solu.
Select all items and click OK.
Now we have the value of reaction about the node 1 and 5 which are fixed. Click Close.
Goto Plot Results >> Deformed shape.
Select Def + undeformed. Click OK
Now we have the deformation plot.
Goto Plot results >> Contour plot >> Nodal Solu.
Under Stress select von Mises stress and click OK.
We have von Mises stress plot.
