I am currently working with your software and noticed that it includes several existing peridynamic models, such as PD Solid Plastic and Correspondence Plastic.
Could you please clarify which plasticity criterion these two models are based on? Specifically, are they formulated according to the von Mises yield criterion or the Drucker–Prager yield criterion?
A brief description or reference to the underlying constitutive formulation would be greatly appreciated.
Thank you very much for your time and assistance.
