Hi Professor, I am a young geotech from Australia and i have been following your channels for years. Could you please talk about more of strain controlled and stress controlled direct shear tests? some textbook only make a touch on these two tests, but never showed any examples.
Great video - as always 😁. I don't get one thing - you said that you packed the sand well into the bottle - so why only at the top the behaviour is as for a loose soil? Is the critical void ratio somewhere in the middle?
maybe its because the bottom part is relatively denser due to the burden of the overlying load , as for the top sand part - it is not overlain by any load - thus it is relatively less dense from the bottom part
Very simple explanation thanks but what about grains that broken during applied the shear I think the change in volume of the sample due to not from rearrangement of grains only but also from breaking of grains during loading
This is the best explaination and demonstration i have seen so far. Thank you a lot.
Excellent.. Great Job👏🏻.. will share your videos with my Soil Mechanics students.. Warm Regards from Bahrain, University of Bahrain..🇧🇭
Thank you so much professor...really a cool demonstration... completely satisfied..You are making geotech more interesting..
Prf....now i truely understand the concept...thank you very much Prf.
This is just brilliant. Yes, soils are cool! Very helpful for my Saturated Soil Mechanics course.
"Aren't soils cool"? hahahah
Thanks for the funny and brillant material, teacher! Greetings from UFPR, Curitiba, Brasil :)
😍very helpful sir
The bottle experiment is so cool. I am doing it with my students! Thanks for the video.
Thank you for your detailed explanation. Very interesting,
This explains the relationship with the soil liquefaction phenomenon?
Very good explanation Thanks 😘
Excellent explanation. Thank you!
Thanks a lot professor for this superb demonstration. May god bless you will a wonderful life.
Thank you very much. Wonderful explanation.
That's a very nice explanation, probably the best. Thank you professor
love you after 'your love with soil engg',
love civil engineering too!
Thank you so much! One 👍 is definitely not enough! Your videos are awesome and helpful!
Thank you so much for your educative videos on Geotechnical engineering.
wow! what an explanation of a difficult concept. Yes you are right. soil is super cool. :)
Thank you !
Impressive video, thank you so much!
finally understood THANK YOU!!!!
a brilliant way of expression 10qu
Why that the shear stress of dense soil drops back finally as their structure turned dense again, but the volume is still getting bigger?

Thank you very much dear Professor

How do we measure the shear strength in a shear box test?
really helpful
Hi
One off-topic question; what is water-rich sand and what is the difference between water-rich sand and saturated sand?
Thanks in advance.
Prof. So nice. Which university do you teach ?
with regards Shivashankar
That is wild.
thanks sir
Loose soil contract and Dense soil dilate, ain't it? 6:43
soils are cool, but rocks are cooler
I always thought rocks were hotter :)
