You taught what my professor took a month to teach me. You are the most loved man at my school, everywhere in the engineering building students have your videos pulled up on your laptops.

You da man Jeff Hanson. Your videos are helping me through an Engineering degree which I used to think I wasn't smart enough to pursue. You're proof positive to the major impact a gifted educator can have on the life trajectory of the disenfranchised. Keep on keeping on Dr Hanson 🤙💪

Here's an chemical engineer student from the south of spain who learns a lot by you. I understand better mechanics of materials and now im ready to pass Material science subject. Cheers!!

So amazing! I always thought of being a professor as a career, you are one of the few people that I look to and other professors should look up to aswell! Learning should be about understanding the material in ways that aren’t going to feel like chores, and you do that very well. Thanks so much for your content!

Fantastic sir! I would like to add that I work in the Auto sector and we design the sheet metal components to be permanently deformed from their inception state of flat sheet metal so that they have the right functionality (toughness, shape etc)

8:45 A dart board and and other similar targets, tears or holes to help open packaging I think aluminum bolts in BMW's N52 engine are designed to permanently deform also because you must replace the bolts when they are removed. And after searching for this, I came across torque to yield fasteners (TTY) or stretch bolts.

One example may be, cylinder head bolts in an internal combustion engine. These are typically “torque to yield” fasteners and are to only be used one time.

Some tapered light poles are mandrel expanded after seam welding which results in a higher strength(strain hardened) permanent deformation worked into the design. Essentially, the pole falls into one ASTM prior to expansion and another ASTM after. Sorry can't remember the numbers but think it's A595 in final form but might be 6 something

Isn't cold-working of metal an intentional permanent deformation?
@rakch148

Car tires are designed to work to some extent under permanent deformation. They are not permanent deformation right out of the factory but they are designed to have some benefit under some permanent deformation(eg. help absorb more impact, maintain overall shape). Without these design you will need to change the tires much more frequently.

My biggest confusion with the stress strain diagram is just in the choice of axes. Stress is the independent variable, strain is the dependent variable. Why isn't stress on the horizontal axis? Took me ages to figure out this graph the first time I saw it...

I'm guessing it is because the Modulus of Elasticity, E, is defined as the SLOPE of the Stress-Strain diagram in the plastic area of the graph, or Stress/Strain.
@Kwintony

It has to do with Young's Modulus, which is just the slope of the stress-strain diagram
