VUSDFLD subroutine for ABAQUS

[Bishal123]

Hello, i am new to this forum

I needed help regarding writing a VUSDFLD sub routine in Abaqus to show the power law between viscosity and shear rate for a range of viscosity value. Please help me how should I write this subroutine?

Start with the documentation chapter about this subroutine - there you will find the information about the necessary syntax. Then look for examples of this subroutine in the documentation (e.g. in the Verification guide). Finally, check if there are any research papers about such simulations that could help you, at least with the theory, formulas and so on.

there is only subroutine for USDFLD in documentations, but not for VUSDFLD. I am not being able to define the shear rate using the subroutine

This one is described under User Subroutines —> Abaqus/Explicit user Subroutines —> VUSDFLD.

Basic examples are under Verification —> User Subroutines —> User subroutine verification —> VUSDFLD.
