This semester, I have a lab for another class that I have this semester. It's pretty fun because we get to break metal pipes and stuff like that with massive machines. Now I know what a 0.5 inch thick solid steel bar sounds like when it's pulled on until it snaps (it sounds like a gunshot)!
Below are a couple of graphs that I created in Excel based on the data collected in one of the labs. They are both stress-strain curves for a steel specimen and an aluminum specimen. Literally, stress is how much "pull", if you will, is exerted on the specimen. The strain is very simple - it's just the amount the material stretches. As you can imagine, steel and aluminum don't stretch very much - you can't even see it.
It's all pretty neat, and it makes a lot of sense. Enjoy the graphs!

Neat, Casey! It must be pretty intense and suspenseful to witness a steel bar being pulled apart!
ReplyDeleteI did enjoy the graphs - very cool!
I am looking forward to hearing more about it and everything else you are doing when I see you next:)!
