BEAM 189
Problem statement:
A cantilever beam is subjected to a concentrated load of 500 lb at its free end as shown. The beam is made of
steel with E = 29(10)6 psi and ν = 0.3. Determine . . .
a. The maximum deflection b. The maximum stress developed in the beam
ANSYS Procedure:
1. Preprocessor > Element type > Add/Edit / Delete > Add > Beam 3 node 189 2. Preprocessor > Material properties > Material models > Structural > Linear > Elastic > Isotropic Enter EX =
29 10 and PRXY = 0.30 3. Preprocessor > Sections > Beam > Common Sections >
(ID = 1, Name = T‐shaped, Pick shape, enter W1, W2, t1 and t2, coarse‐fine = 0) 4. Preprocessor > Sections > Beam > Common Sections > Preview
5. Preprocessor > Modeling > Create > Keypoints > In active CS
Key point X coordinate Y coordinate Z coordinate 1 0 0 0 2 60 0 0 3 30 ‐10 0
6. Preprocessor > Create > Lines > Straight lines (Click on keypoints 1 and 2 to make line 1)
7. Preprocessor > Meshing > Mesh tool > Element attributes > Lines > Set > Choose line > OK > Pick
Orientation key points (check Yes) > Apply > Pick keypoint 3 > OK
8. Preprocessor > Meshing > Size cntrls > ManualSize > Lines> All lines > NDIV = 20 > OK 9. Preprocessor > Meshing > Mesh > Lines > Pick All 10. Utility menu: List > Lines > Orientation KPs 11. Utility menu: Plotctrls > Numbering (Turn element numbering on) 12. Utility menu: Plot > Multiplots
13. Utility menu: List > Elements > Nodes and attributes
14. Utility menu: List > Nodes
15. Utility menu: Pan, Zoom, Rotate >Click on ISO > Close
16. Utility menu: Plotctrls > Style > Size and shape > Select the radio button next to /ESHAPE > OK
Applying loads 17. Solution > Define loads > Apply > Structural > Displacement > On key points > (Pick first key point and fix all
DOF) 18. Solution > Define loads > Apply > Structural > Force /Moment > On key points > (Pick key point at the end of
the beam and apply Fy = ‐500)
19. Solution > solve > current LS Post processing 20. General Postproc > Plot results > Deformed Shape > Def + Undef edge
21. General Postproc > Contour Plot > Element Solu > Stress > x‐Component of stress > OK
Summary of results:
a. Maximum deflection: 2.564 in b. Maximum stress developed in the beam is 96,512 psi (compressive) at the bottom of the web at fixed
end.
