buckled I-beam

thingiverse

This is the severely distorted shape of a buckled I-beam after the flanges and web have begun to collapse. As a computer structural analyst, I've taken time off from work to avoid the coronavirus, so naturally, I had to take on this project. You will need to incorporate supports to stabilize the structure. ============ TECHNICAL INFORMATION --- GEEK WARNING --- W 12 x 65 I-beam AMS 5643, 17-4 PH stainless steel, H1150 Note that I-beams are not typically made from this material; however, these properties were easily accessible through open-source information. The analysis was performed using ANSYS ED 10 Classic with the following settings: - Brick-walled on the left - Enforced downward displacement on the right - Large displacement enabled - Multilinear kinematic hardening applied A Ramberg-Osgood approximation was used, which may not accurately simulate a real stress-strain curve. The simulation ran to 10 inches of forced deflection. The strains exceeded the elongation limit, and brick-walled constraints were applied on the left side. Holes near the diagonal tension area were introduced due to extreme thinning, which was less than the filament width. ANSYS scripts I wrote were used to convert the deformed geometry from ANSYS "upcoord" to an .stl file. SketchUp was employed to add a fake wall for added stability.
