Week 9 Tension and Torsion test challenge
Machining-Planar
Aim
To model a simple machining model system and determine strains and stresses.
Procedure
- Start a new explicit dynamics model in ansys and import the model
- Add the materials as shown.
- Open this model in ansys mechanical.
- Assign Steel-1006 to the workpiece
- Create 2 coordinate systems as shown.
- Create type of mesh and set it to complete tetrahedron elements.
- For the 2 faces, create face sizing of 3mm with sphere of influence as shown.
- Generate the mesh.
- Define the displacement along X axis and set y/z to 0.
- Define fixed support for the workpiece.
Analysis Settings
Set the analysis settings as shown.
Set your output blocks as shown
Userdefined Result:
For the torsion case, create a cylindrical coordinate system for rotation.
Create 2 extra face sizings to refine the critical areas with a mesh size of 1mm.
Define the rotation
Post Processing
Case 1:
Tension
Case 2:
