very helpful, thanks!
helpful
You have saved my life. Such a wonderful tutorial !
My pleasure 😊
thank you very much!
Tnx for the great video. Do you know how to simulate crack growth in hyperelastic models sir?
You are a saviour
Thank you :)
Dear,
That was a great video. Can u make a similar video on XFEM crack in 3D? I also wanted to learn about the application of fatigue loading (using R, at Higher amplitude).
Thanks.
I do not think that there is a problem there.
Hello sir,
Thank you for your videos,
I'm working on a fatigue test on steel specimen and i want to visualize temperature in the crack tip during the propagation phase. Is that possible in abaqus?
Thank's,
Hello, this would be a very interesting simulation. I have no experience with such model though.
Thanks !
Welcome!
Thank you for the nice video. Is there any reference limit to the smaller circle on the crack tip ? Also will it affect the results if the dimensions of these circles are changed ?
Good question. There are some norms. Best practice is to try to keep the aspect ratio of the elements close to 1.
@@FaisalQayyum Thank you
hi sir, can you say how will you draw a graph if we are comparing experimental data and numerical data if we are collecting experimental paper from other author because we dont have exptl data point only we r having is the numerical data..............please say
That is an interesting question, the contour integral approach yields J-Int or SIF on the crack tip and experimentally we obtain CMOD, crack length and applied force. This data is analytically processed and plotted together with a similar reference. Please take a look into my previous publications for more details:

How do wedge elements work in the crack field? I keep getting error
What's the error that you're getting ?

Why drawing the two circles
