UMAT subroutine for SMA

[zidane.imade]

Hello

I try to write a UMAT subroutine for shape memory alloy material.

Does anyone have a UMAT subroutine for SMA material? In order to understand how I have to write mine. Could anyone help me please?
Any help is welcome.
Thanks.

Do you need it for Abaqus ? It has a built-in superelasticity model for shape-memory alloys.

Yes I need it for abaqus, please

As mentioned by FEA way, there is a supported superelastic material model for Abaqus so why are you looking for a SMA UMAT to use with Abaqus? What limitations does the currently supported superelastic model have? Given that you are looking online and assuming you really need a new SMA UMAT, odds are, your best bet is to partner with someone who knows how to write UMATs.
