Excellent lecture! Really helped me learn. Thank you UNSW!
I really wish the education was free everywhere. Thank you so much for the generous effort of sharing thins :)
proud to be a UNSW Aerospace alumni :) Cheers Dr. Garth!
205:00 to 2:12:21 - Importance of ABD Matrix elements - was very good. Thank you
Solid info. Well presented
This Chanel is amazing!
Excellent Lecture. Thank you Dr.Garath.
Quite useful for anyone who wants to refresh their basic knowledge on composites.
Thanks for the video! Really helps me brush up my mechannical engineering knoledge!
Apparently not your grammer though lol
Would be great to see correlation between these derivations and calculations with Test data.
Thank you Prof. Garth. This lecture helped me a lot in clearing my basic doubts about the composites. I would also suggest you to post your lectures on Micro mechanics and Macro mechanics if possible. Thank you once again sir!
do you know macro and microscale? can you send to me: shipbuilding_dta10@yahoo.com
holy cow! 3 hours class. must be tough.
Thanks Doc very informative
How important multiscale technique is to predict failure of composite materials? In practice, do engineers prefer classical analysis approach? Or, are they also considering multiscale techniques?
Do you have any good resources for calculating the mechanical properties of a woven lamina (like twill weave) ? instead of a unidirectional lamina. Thank you
Extremely informative and well-presented - thank you! But, somehow the Q12 and Q22 terms seemed to have been switched at ~2:14 from what they had been shown at ~1:19 and the Excel sample at ~1:34.
I want to do research @UNSW
how can i get subtitles ?, thanks in advance
Sir, do you have any latest video on composites..
Good
There´s just a minor error, on the slide at 1:30:31, with the LHS of the matrix in 2nd matrix equation [(6x1 = (4x4)(4x1)], isn´t there?
Liv Yi It is 6x1 = (6x4)(4x1) There are six separate rows in the matrix. Daniel and Ishai is a really great book for this analysis.

Thank you so much
This Composites saves
FUEL.
Are there any breaks edited out or did Garth present for a solid 3 hours?
cupmike Two 10 minutes breaks edited out. It is still tough to teach though.
I've read it is wrong to bond carbon fiber to fiberglass because they have different strain resulting in one failing before the other.
Also, I've seen hard points(metal bushings) embedded in fiberglass and carbon fiber. Is this a bad practice? I've seen holes drilled into a carbon fiber spar and bushings embedded for hard points. Is this a bad practice?
Very bad practice indeed.
We lay the metal hard points for bushes and fixings etc in the very beginning stages when the fabric is being layer in the mold.
To lay it, cure it, bake it etc and then cut holes out of the media is entirely the wrong way to go about things.
On the other hand, I work with guys who are very worried about tenths of grams and thousandths of seconds so we really have to output the closest-to-perfect items imaginable.
If you’re making decorations and toys and items that dont have the ability to make or break billion plus pound contracts, you can treat it like plastic and drill and cut whatever you want because it’s not that important.
Judge it on a case by case basis.
When you were an hour and fifty minutes in and just STARTING CLT I felt pretty bad for ya haha
CLT - 1:50:32
Is there anyone working on how to create low density, flexible and strong tensile materials to improve earthquake resilience in construction?
Better yet, buy a house in an area NOT prone to earthquakes.
Carbon fiber toilet seats!
How come no one noticed the error at 2:00:15 slide, line 3(shear strain). The dx, dy must be interchanged for the first two terms(Uo,Vo)
Good pick-up. I've just fixed my slides. I'll be delivering this lecture again in a few weeks to a fresh batch of 3rd year Aerospace Engineering students at UNSW.
Not a lot of people understand shear.
The transition from elastic to plastic goes over most of their heads.
If you have a Carbon Toilet Seat in your RV or Airplane. You will get improved Fuel economy. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Over cheap lightweight plastic? No
I can't sleep. Anyone else?
WHY THE FUCK DO I SEE IMPERIAL UNITS?

I honestly wouldn't mind switching to Mandarin.
