Missing points 7:20 (ish) Go to assembly - instances - part - Right click and select make independent prior to assigning crack 12:11 (ish) Go to History output, create new, set domain to crack, set number of contours as needed, select J integral prior to submitting job

The best crack simulation!!! Thanks for you sharing. Could you please explain more why you apply those boundary conidtion, one is on the right side (fixed on Y), bottom is fixed in X, Y?

[@Professor3MEC]

Thanks. If I understood correctly, just to avoid rigid body motion.

[@sunils1056]

Thank you for the excellent tutorial. I would like to know if increasing or decreasing the diameter of the partition would alter the SIF ? Or is the SIF sensitive to the mesh we use and to what extent ?

[@Professor3MEC]

Yes, it may. Also plasticity would change everything too.

[@dineshchejarla1012]

Hello sir, Your videos are a blessing! Can you please show an example of how to mesh 3D through cracks? Thank You, It will really be helpful for my simulation.

[@Professor3MEC]

Thanks for finding the stuff on this channel useful. I will do soon.

Can you please send me the link of the video where you properly mesh a 2d crack to get the k1 value ?

[@Professor3MEC]

Here are the few links which may help you partition your geometry and then mesh it as you would like. kzbin.info/www/bejne/bJekhp6DgLChpq8 kzbin.info/www/bejne/ooqzimaDaMhsoZI let me know if you need any thing further. All the best.

@@Professor3MEC thank you but please i want a tuturiol for how to mesh a 2d crack to obtain the k1 value like you did in this video

[@Professor3MEC]

I will try to make one ASAP

My J integral values and the J integral estimated from Ks is coming very different, is it normal? what is the difference between the two?

[@Professor3MEC]

Are you using elastic plastic material? As for linear elastic solutions both should be approx. same.

@3MEC Sir Could you please send link for how to calculate values of J integral and geometric factor in abacus

[@Professor3MEC]

Do you mean abaqus documentation?

[@sachinsingh5142]

How do we decide which shape of element will give best result for that particular analysis?

[@Professor3MEC]

Its a very broad topic and highly depends upon the type of analyses being done. Also, it is very important to understand element formulation to get a feel of what are it's limitation. Best is do mesh and element sensitivity analyses while look at documentation for specific tips and tricks on the type of element being used. So it's not a straight forward black & white answer.
