ANSYS TUTORIAL Analysis of a Simple Cantilevered Beam with End Load Copyright 2001-2002, John R. Baker In this tutorial, you will model and analyze the beam below in ANSYS. Step-by-step instructions are provided beginning on the following page. If you run into problems with these instructions, feel free to contact: John Baker; Phone: 270-534-6342; Email: [email protected] The steps that will be followed are: Preprocessing: 1. Change Jobname. 2. Define element type. (“BEAM3”, which is a 2-D beam element) 3. Define real constants. (Area, Moment of Inertia, Height,SHEARZ) 4. Define material properties. (Young’s Modulus, EX -- only property required for this analysis) 5. Create nodes. (21 total) 6. Create beam elements between nodes. (20 total) Solution: 7. Apply constraints and loads to the model. 8. Solve. Postprocessing: 9. Plot deformed shape. 10. List reactions. 11. List the deflections at each node. 12. Define element table items for plotting and listing of various stress components. 13. List element table items. 14. Plot element table items. 15. Exit the ANSYS program. _____________________________________________________________________________ Note: Beam Material Modulus of Elasticity = 30E6 psi

Note: The instructions below include alternative command line entries that can be ignored if you choose to use menu picks to perform the required tasks. These are provided for your information. You may find that it is sometimes more convenient to enter certain commands directly at the command line. ***AS YOU WORK THROUGH THIS TUTORIAL, WITHIN ANSYS, ON THE ANSYS TOOLBAR (UPPER RIGHT) CLICK ON “SAVE_DB” OFTEN!!! Preprocessing: 1. Change jobname: File -> Change Jobname Enter “beam”, and click on “OK”. Alternative Command Line Entry = /filnam, beam Also, to enter the preprocessor, at the command line, enter: /prep7 2. Define element types: Preprocessor -> Element Type -> Add/Edit/Delete Click on “Add. .”, highlight “Beam”, then “2D elastic 3”, click on “OK”, then “Close”. Note that, in ANSYS, this element is sometimes referred to as “BEAM3”, because it is element type 3 in the ANSYS element library. Alternative Command Line Entry = et,1,3 3. Define the real constants for the BEAM3 elements: Preprocessor -> Real Constants -> Add Click “OK” for “Type 1 BEAM3” The appropriate values for the given geometry are: AREA=8; IZZ=(32/12); HEIGHT=2; SHEARZ=(6/5). Leave the other fields blank, and click “OK”, then close the “Real Constants” box. Alternative Command Line Entry = r,1,8,(32/12),2,(6/5) Note that the “1” following “r,” denotes that this is real constant set number 1. Also, the “SHEARZ” term, entered as (6/5), allows shear deformation effects to be included in the solution. The value used is appropriate for a rectangular cross-section. A different value would be required, for instance, for a circular cross-section. This term can be left blank if shear deformation effects are assumed to be negligible.
