I want to model behavior Shape memory material (SMA) in Abaqus .diagram stress-strain material is like this picture. This graph is adiabatic condition (because is high rate loading like earthquake) and is simple multilinear model for theses material. Point A, B, C, and E is defined. Temperature changes between Ts and Tf .slope branch EA is equal elastic modulus Austenite (67000Mpa) and slope branch BD is Martensite (26300Mpa). Elastic modulus changing in process analysis .Ts is start Temperature .Tf is related with effective specific heat, specific entropy at the reference state. Temperature defined in each branch graph. Equations of stress and strain are according to Temperature.in figure 3D point 0 ,1,2 is shape memory effect (Temperature is Ms
Hi Elham,
Hope you find this link useful.

Hi Dr Miguel Angel Callejas
thank you .that is very good.I could not download the file( 1658.pdf and 4699.pdf) on this site.I think the file is very useful for me.can you help me?
regards
Dear Elham,
The files are there...you just need to read carefully. If you don't get it, tell me and I'll help you.

Hi Mr Miguel
I want open this file ,message is :the file has been damage was not correctly decoded.I don't get it .I sent message for frank.I waite for him to answer.can you help me ?
thank you so much .
Yes I can. You should read carefully as I told you. The files are right there. I'm sending you a message.

Hi Mr Dr Mig
I have question about link Abaquse to Fortran. I am using from cod of Fortran for behavior material SMA . I have Subroutine from SMA behavior in Fortran.(file SMA_UM) I do not understand the process, but I read this Subroutine. do you have information about the Algorithm step by step SMA behavior ?
thank you so much
