lamb waves are the propagation of energy through a structure, you can imagine that if you hit a piece of concrete with a hammer the wavelength of energy will travel through it. It is far from trivial to measure or model. There is only one thing in the world I know of that is capable to measure them actually.

this, however, makes me happy in the pants

I don't like the non-fastback cars and vinyl roof's are teh lame.

Epic steak is epic...40 oz of pure bovine love

That looks like a roast and not a steak. Unfair since I dropped 6 bills on three of us for dinner at Carlos & Johnny's.

Theres places where food costs that much!?!?!!!??!!!!!

Holy crap, thats about half of what my truck is worth.

Looks like a rib steak maybe... I dunno, not something I'd eat.

T-bone & sirloin, thats it. Mind you, I've never bought a steak at a grocery store, all grain fed right from the farm.

ya the pumpkin chuckin stuff is sweet seen it like twice on tv, and the nuematic cannons are the best!

i think it's pneumatic

the Romanian spell checker strikes again

makes me laugh every time he corrects someone

$600 damn!!!!!

not my money

Sam Adams Boston Ale is rather tasty...

i think its craqp

What are some good imports for me to get for friday night? Just some off the top of your head if you could, there is a liquor store here with a lot of imports so I might get lucky on finding something there.

what do you actually like?

With that bone structure it is not a "steak". Chuck steaks are not steaks but roasts.

Off to measure strain

I'm sure your way of doing it is way cooler than what we do in my unbelievably boring Solid Mechanics labs

Are you laying gauges?

I've help lay more than one or two gauges on concrete specimens.

We just use lasers. Can measure the stress, strain, and lamb waves

if you find either stress or strain, the other is pretty damn easy to get

no clue what a lamb wave is though

It is very possible to find strain and have no stress. Think of the edge of a plate being stretched in one direction...

how can there be strain but no stress? They're proportionally related through Young's Modulus.

lamb waves are the propagation of energy through a structure, you can imagine that if you hit a piece of concrete with a hammer the wavelength of energy will travel through it. It is far from trivial to measure or model. There is only one thing in the world I know of that is capable to measure them actually.

and let me guess, you sell it?

We haven't even touched on vibrations yet

Not true. For an infinitely small defined structure like a wire I agree, but not so with a plate.

that must be nice.

yeah, the fast back would definitely be better, but I'm not going to complain about a 396 Caprice

and I actually don't mind vinyl roofs on most cars

We haven't even touched on vibrations yet

Since they are dynamic it is by default a vibration whether the measurement be done in displacement, velocity or acceleration

well this is certainly beyond the scope of my classes so far

It is, you can definitely tell the difference. Now, I am going to remove a steak from the freezer so I can marinate it for 24 hours & eat it tomorrow for supper, mmm.

I've got some in the fridge right now.

We haven't even touched on vibrations yet

that explains it

we've only done dynamics on a very basic level

what do you actually like?

Honestly, I don't know. Normally I drink bud light/coors light/something along those lines. Rather a fan of the local red ale, and wheat beer though. The scope of my beer experience is a very narrow and dark path.

I do have some beers brought back to me from the Czech Republic that I need to drink sometime.

Scott you should send some of that meat my way. I'll pay .

you damn engineers make me kinda regret changing majors....but only for a few seconds

Party in here tonight.

Don't ever regret that....
