Abaqus: Rolling Contact Fatigue Modeling
zhlédnutí 7KPřed 9 lety
NOTE: Watch this video at a lower speed. This video shows the localized, elastic-plastic, subsurface von-Mises stress-fields during rolling contact fatigue (RCF) phenomenon. Such Hertzian contact stresses are induced when two machine components come in contact during load transfer. These are responsible for failure of bearings, rail wheels, gears etc. It can be observed in this video that only ...
Parallel Axis Theorem Example problems
zhlédnutí 27KPřed 9 lety
This video is an extension of discussion on the Parallel axis theorem. In this video some simple composite shapes are used to illustrate the calculation of moment of inertia of beam cross section using parallel axis theorem.
Parallel Axis Theorem
zhlédnutí 84KPřed 9 lety
This video describes a method to calculate the moment of inertia of composite bodies using parallel axis theorem. Moment of inertia of a beam cross section is required to in beam bending theory to calculate the stress.
Centroids of composite bodies

This 15 minute video demonstrates the method for determining the centroid of a composite body. This is the first of the three videos.
Thank You
Its wrong, because I= 1/12 bh3
its not correct if axis that you are going to calculate inertia upside of your figure the formula I= Ic-A.d^2 its downside of figure the formula I=Ic+A.d2 okay lets calculate for this example first Ic=bh^3/12 u know, 150*10^3/12 = 12.500 Now lets try to calculate this answer from another way . i.pinimg.com/originals/21/71/c7/2171c7dd7b545d4b762f34e5e5be06c2.gif I=bh^3/3 (its for axis that tangent rectangles down edge.) I=150*10^3/3 == 50.000 IC= I - A.d^2 == 50,000 -(150*10)5^2) Ic = 50.000 - (1500)*(25) Ic=50.000-37.500 Ic = 12500 Now as you can see when axis is upside, the formula --- Ad^2 downside the formula ++Ad^2
Sir I like u'r video, can u please make a tutorial on how you do it?
hello mr. would you mind if u send me your email i need some help from your research area in physical modelling of the rolling part using abaqus and some other questions...
hello,Mr Anup Pandkar.I have read your article. I havesome problems in it. Would you please send me a your Inp file? Thank you, my email address is dongll92@163.com
What is the name of this channel?
Hello, Mr Anup Pandkar. I´m impressed by you work. It´s very interesting. I would like to contact you by email to request your help and advise about how to setting up abaqus to perform this simulation. Thanks.
Hi Fendix, Thank you for your comment. Please add me to your LinkedIn network and let me know your questions. I will be happy to help.
Thank you very much, the explanation was clear and understandable.
Thank you sir
Amazing work sir, How do I carry out rotating bending fatigue test on Abaqus??
You're awesome man, I wish you can be my Professor!!
Nice series of lectures Anup
MOI of that I section was just superb, less time consuming and simple. Thanks (Y)
i like this lecture.... it was a great lecture for MOI and PAT.
Sir I have a problem ...as the moment of inertia of an object is quantity expressing a body's tendency to resist angular acceleration... If i am right here then moment of inertia should be find out for a body which are in rotation.... But you took an example which haven't angular acceleration... Please clear my doubt if any one know
Thank u sir for this video
Wonderful sir, cleared the concept.
Very nice video, what if the body is consisted by 2 different materials? an i beam which the top and bottom flanches are from one kind of wood and the rest is from an other , is there a way to calculate the bending stress of this member? also a way to calculate the shear stress that happens on the glue bonding them together?
Thanks a lot sir ..... from faridabad .....
Bravo... this made things simply easier... Thankyou
thank you sooo much :D
Sir Unit of Moment of interia is m^4 ?? How its possible??
Notice the formula used for calculation of MI has b*h^3 in it. Both b and h have units of length i.e. meter. So bh^3 becomes m^4. Hope this clarifies your question.
Dimention of area is L^2 and in MOI area is multiplied with square of the distance so L^2(for area)*L^2(for distance square) gives you the dimention as L^4.
Awesome job!!! This was the only concept i was struggling with for my 2nd deformable bodies exam and these three videos made it so clear. THANKS!!!!!
sir please upload video on perpendicular axis theorem
nice videos
thanks that was a good lecture
God bless you sir for such a wonderful explanation
Thanks a lot
THANKS BRO. best video in the CZcams about 'Moment of Inertia' and 'Parallel axis theo. and their applications ..
thanks a lot , bro for great explaination ..
nice explanation but cameramen keep moving camera is really annoying
where is the mass of the body at (in the final term) ? i must have learned it another way maybe .. great explanation by the way
thanks for this video n the before one
thank you very much .
Thank you very much very helpful.
thanks sir...
extremely helpful Anup.
very clear
Best video in the CZcams of 'Moment of Inertia' and 'Parallel axis theorem'. Thanks a lot
ञ
nice lecture
wow very nice explanation
In example 2, we should subtract solid and smaller square is solid too, Smaller square should not be hollow. Correct me if I am wrong
Very well explained!! Thanks a lot!
Great explanation!!!!
how did u get 13.75 ??
good work bro. i like it & Thank you so much.
Anup, Could you fix your second half of the parallel axis theorem? It should read bh3 not bh2. Beside, the explanation is awesome.
+Sagar Singh : I have added a note that corrects bh2 to bh3. Hope this clarifies your concern. Thanks for watching :-)
100thanks
Good woork, would you like to send the tutorial or inp file, my email is cheikensmm@gmail.com Thank you
