Thank you so much, dear professor. The best fracture mechanics material available online.

[@juliojoseguzmanperez4579]

Thank you very much from Spain professor Dr. Ramesh. I was really struggling with this topic in class

[@MrLunchbox88]

Thanks for a fantastic, well explained and thorough lecture.

[@desperados988]

Awesome. Thanks from Italy.

[@fendix975]

Excellent video. Congratulations!!!!!

[@mono7891]

Great explanation!

Thank you for the generous sharing professor, I find it very helpful

[@madhusuthananm3494]

Thank you for simple explanation

[@mono7891]

What if I do not know the "Force" and just pulling it upward with a constant displacement? How shall I find the J-integral in that case?

[@prathameshgogate9289]

Thanks for the video Sir!!

[@Mendo.anshul]

Thank you so much for this explaination with such in delailed manner!

[@GauravKumar-np2qm]

Where is its english version?

[@mono7891]

Is it okay to publish this equation in a thesis??? If not, who shall I ask for permission? Please guide me to Dr. Ramesh.

[@MARCIOROOOTS]

Thank you for sharing, sr. !

[@akdtmani]

Thanks it is very useful however after around 15 mins of the video it stops and does not move forward at all please fix it.

[@madhusuthananm3494]

Very clear

[@filippocardoso7977]

What is the B term at 31:00?

[@mssaber77]

B is the thickness of the beam.

[@rajeshprasad101]

It is not clear how the path for the integral can have sharp corners. Definition of J requires the normal n to the curve and Traction T on the plane tangent to the curve. Neither the tangent non the normal at the sharp corner is defined.

[@andrewjensen7454]

Integrate along each straight path separately, then sum the results for the full integral value. This is what he does in this video, as the path can be arbitrarily chosen and will still yield the same final value. There is no requirement that dn/ds be continuously differentiable along the path.
