UMAT subroutine help for li-ion battery lithation process

Submitted by nadeemqasr on
research

Hi everyone,

I am trying to run simulation of lithiation in anode material used for li-ion battery. To encounter for plastcity; it needs UMAT subroutine.

Can anyone help meto make this subroutine (as I am not good in programming :() 

..?

 

Thanks

Why can't you use *PLASTIC ?

But if you really want to: how to rewrite *PLASTIC as UMAT you can find in the Example Problems Manual

1.3.16 Upsetting of a cylindrical billet: coupled temperature-displacement and
adiabatic analysis 

 For subroutine basics Get the file
