bilinear elastic constitutive model

[Lina-16]

Hello

I would like to introduce a bilinear elastic constitutive law.
Is there a way i can define it other than by a VUMAt subroutine?
I need the elastic modulus for the second part to be greater than the first one.

Thanks in advance
Lina

You should be able to define the modulus as a function of a field
variable, then change the field variable value during/between load
steps.  See *FIELD and *ELASTIC.

Regards,

Dave

Hi Lina,

I have a question on Abaqus and i need help....i have to create a 2D model
with some specification and i was wondering if you can help me please....if
