What Type of Bottle Opener Works Best? Solved Using Finite Element Analysis Simulation

Here is a fun project that I've been working on for many months where I've modeled the process of popping the cap off of a beer bottle. While I was at it, I figured I might as well determine what type of bottle opener works best. So I modeled a bottle and cap, as well as four unique bottle openers, and determined the amount of force that needed to be applied to each opener to pop the cap off. The bottle openers I looked at were a keychain opener, corkscrew, one-handed opener, and a batman bottle opener. I created the models from CAD which I found on grabcad.com and performed finite element analysis simulations using LS-Dyna. I also rendered the d3plot animations of the final cap pop simulations using Blender which turned out really nice looking! As only an engineer would do, I truly over-did this project and spent way too much time fine-tuning the simulations to get results in the ballpark of what I expected to find experimentally. I even created all of the models in this video using only the free to use program LS-PrePost which was used to clean the CAD geometries and created the model meshes. This project was a lot of fun and I actually learned that LS-PrePost is extremely useful for someone looking for a free program to create models like these. Please let me know if you enjoyed this video. A lot of effort went into this project and I appreciate all comments!
