Dear Prof. Cemal Basaran,

Thanks for sharing. Can I ask you a question?

Can Zerilli–Armstrong model or Johnson-Cook model predict localized plastic failure or damage such as shear band failure or necking failure and location? Like our recent work   " Revisit initiation of localized plastic deformation: Shear band & necking "     

I am new and but also very interested in fatigue life prediction models for metals and polymers. Is there any work relate to fatigue damage to microstuctural changes of metals or polymers?

Thank you again,

Lixiang

Dear Prof. Yang;

Both of these models you mention are empirical curve fitting models. If you have a test data you can fit them to these functions and even if they don't work you can add new parameters to curve fit to your data. In my humble opinion, that is not science. I realize that, now it is called "Data Science".  :-)

Best Regards

Hello Dear Prof. Cemal Basaran,

Thanks for your input. Unified Mechanics Theory is interesting.  I am trying to find your new published book to understand more about it. Is damaging factor connected to thermodynamics or entropy?

Best Regards,

Lixiang
