ABAQUS built-in SMA model
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.
vuinteraction sumroutine
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
Manipulation of SDV in VUSDFLD subroutines
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.
Call for Abstracts TMS 2016: Biological Materials Science Symposium
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
Conversion of gemotry in beam section
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

Abstract:
UMAT subroutine for 3d solid elements
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

Postdoc position: Phase field models for inelastic deformations in materials
A Postdoctoral position will likely be available at The Johns Hopkins University, Baltimore, U.S.A. in the area of phase field modeling of inelastic deformations, including fracture, under extreme thermomechanical loading conditions. The potential candidate should have a Ph.D. in engineering or physical sciences disciplines, background in numerical methods, intensive experience related to a topic in multiscale simulations of materials.
PhD Position in Arterial Biomechanics and MR Imaging in Trinity College Dublin
The aim of the research project is to develop a means of identifying alterations in collagen fibre architecture of arteries in vivo using non-invasive imaging techniques that can be linked with disease progression. DT-MRI has been used to characterise fibre patterns in animal tissue and this project will explore the means by which this can be enhanced in human tissue. Potential applications of the NODDI (neurite orientation dispersion and density imaging) protocol in arterial tissue will be explored.
