Dear Mechanicians,


time and again the question of SMA (shape memory alloy) modeling pops up.

In ABAQUS, you can achieve this only by (V)UMAT coding or by using the little-known built-in SMA model.

In the past I have frequently responded to queries on SMA modeling and could refer to a customer help site of SIMULIA. That site is down, regrettably.

I decided to post the files here to avoid responding with a longer explanation to every individual seeking assistance and uploading the files as E-mail attachment every time.

hi dear friends

i must learn to work with VUINTER and VUINTERACTION subroutines.plz help me...

is there any body who knows how to work with these codes??

best wishes

I am trying to write a subroutine with VUSDFLD

I would like to manipulate the Solution Dependent Variables based on its previous value as follows:

Statenew(k,2)=Stateold(k,2)*10

But Multiplaction and Divisiion operations do not give any results. They give 'No value' when they are output.

Would anyone know why this happens?

Thank you.

We are organizing a Symposium on Biological Materials Science at the 145th TMS Annual Meeting & Exhibition (TMS 2016)

February 14 – 18, 2016 in Nashville, Tennessee.

This symposium will encompass the following themes:

• Biological materials (soft and hard tissues, cells, etc.)

• Biomaterials (implants, tissue engineered structures, and devices)

• Modeling and experimental evaluation of mechanical properties of biological and biomaterials

• Biomimetic and bio-inspired materials

Dear all,

In ANSYS mechanical I am interested for free vibration analysis of ship structure, for it I have an weight distribution information along with all geometry details . I am looking for frequency as a an output from it. 

I want to convert the ship into equivalent beam section ,anyone has an Idea how to convert it into beam element ?

As per my knowledge I have to take care of CG location ,Ixx ,Iyy and Izz.

Kindly help me to perform same.

Regards

Dear All,
I am okay in ABAQUS although trying subroutines for the first time.
I am trying to modify some codes available online, but the primary UMAT which I am posting here, is not working.
It shows no error in .log file but the job monitor says "Problem during compilation - D:\Abaqus Work Directory\Trial_user_subroutine\try\Umat_mine.for"

Please help me this, its very urgent.
Thanking you all,
P.S. The code is attached in .txt format
Here is the code
