Dear Jose Marques Basilio Sobrinho,

I am not sure if there is a simple and definite answer to your questions, as the description "best" is totally subjective. For example I use Abaqus since it provides me with the capability of creating a User MATerial (UMAT) subroutine that can implement any model as well as I can perform variations regarding the constitutive equations (a tutorial on how to write a UMAT or a VUMAT is available here: https://imechanica.org/files/Writing%20a%20UMAT.pdf ). As far as I am concerned ANSYS has built-in material models developed by Auricchio et al. (you can find more information here: https://www.sharcnet.ca/Software/Ansys/16.2.3/en-us/help/ans_mat/smas.html ). Finally, as far as I know, latest Nonlinear Structural Materials Module of COMSOL offers the capability to use the models of Lagoudas and Souza–Auricchio.

Kind regards,

Anargyros

Thanks for your response Anargyros A. Karakalas .

I have been working with ANSYS for some time.

I will check this UMAT capability on ABAQUS.

I have been used ABAQUS for my master thesis. In 6.17 or newer versions of ABAQUS you don't need to write subroutine (fiqure) . I'm abaqus and Ansys user and i prefer use abaqus for usual simulations such as bending or twisting problems and use ansys for fatigue or fracture of SMAs.

Hosein Tavangar, grateful for the information.

Just for balance MSC Nastran and Marc have specific shape memory alloy material definitions which mean you don't need to define your own UMAT's. I can't claim which is best.
