Save

It would be of best interest, to save the project at this point. Click on the "Save As.." button, Image Removed, which is located on the top of the Workbench window. Save the project as "Cantilever". When you save in ANSYS a file and a folder will be created. For instance if you save as "Cantilever", a "cantilever.wbpj" file and a folder called "cantilever_files" will appear. In order to reopen the ANSYS files in the future you will need both the ".wbpj" file and the folder. If you do not have BOTH, you will not be able to access your project.

What's Under the ANSYS Blackbox?

To understand the framework of what's under the ANSYS blackbox, go through the videos in the “What’s Under the Blackbox” section of our free online course on ANSYS-based simulations. Registration is required to access this course. We'll be using this framework in this tutorial.

Check Your Understanding

One or more of the following statements is/are true. Select which statements are true.

  • 3D Elasticity theory makes the assumption that plane sections remain plane whereas the Euler-Bernoulli beam theory doesn’t make this assumption.
  •  In Euler-Bernoulli beam theory, the Poisson's ratio is assumed to be zero.
  • If we have 4 nodes instead of 3, ANSYS will need to determine 8 parameters (4 y-displacements and 4 rotations) either from the essential boundary conditions or by solving a set of algebraic equations. 
  • If we have 4 nodes instead of 3, the number of algebraic equations that ANSYS will need to solve simultaneously will be 5.
  • We have to determine the y-displacement of the midline at locations between the nodes using interpolation. This interpolation is given by a second-order polynomial.
