Can you please guide me on how to use the Lade's single hardening material model in Abaqus (what is the name of the model in Abaqus)? I could not find it explicitly.
It's not implemented in Abaqus so you would need a subroutine. Check the article "Application of the Single Hardening Model in the Finite Element Program ABAQUS" by K.P. Jakobsen.
