Dear All,

I am working on the superplastic forming of a rectangular box for which the material properties are defined via a user defined creep subroutine. The user defined creep subroutine is for Abaqus Implicit/standard. The loading is done via Visco step in which there is an option for creep integration

    Creep/Swelling/viscoelastic integration

                                1.Explicit/Implicit  

                                2.Explicit

So there is confusion in my mind that already we are working in Abaqus implicit(the Abaqus solver is implicit).So, what is the point of this option(implicit/explicit and Explicit)?

thank you,

Best regards,

Tabassam
