The Interdisciplinary Centre for Advanced Materials Simulation (ICAMS) is a new research centre at the 
Ruhr­University Bochum, Germany. At ICAMS an interdisciplinary team of scientists from engineering, 
materials science, chemistry, physics and mathematics is working on the development and application 
of a new generation of simulation tools for multi­scale materials modelling. 

Modelling a spring shape memory alloy

Shape Memory Alloys

Hello,

I am a Masters student and I need to model a spring shape memory alloy in ABAQUS. I have found a UMAT file,however the file contains the geometry of a 1X1X1 cube. Does anyone have any idea of how I could copy the geometry of the spring(which i modeled in solidworks and imported to ABAQUS)into the input file of the cube,so that I could run the model in ABAQUS. I have tried this but ABAQUS is giving me errors

Or does anyone have any other idea of how I could model a Sping SMA in ABAQUS?

Thanks

Akin

 

 

Temperature dependence of the thermo-mechanical properties of aluminum

Temperature dependence ; thermo-mechanical properties ; aluminum

I'm looking for the thermo-mechanical properties of aluminum, such as  Young modulus, thermal expansion coefficient, thermal conductivity coefficient and poisson ratio as a function of temperature :

E=E0(1+E1*T+E2*T^2+E3*T^3)  ;  T: temperature in K

For sheet metal forming, how to calculate the shear stress in VUMAT?

Submitted by meshfreer on

 Hello, veryone. I am usint the VUMAT to define a new material behavior. There are questions about the calculation of shear stress.

The sheet metal forming was took as a plane stress problem in many relevant articles. So only three stress components:sigma_{11},sigma_{22},sigma_{12}

(sigma_{33}=0)are included in stress apdate algorithm such as the return mapping algorithm(J.C SIMO, R.L. Taylor. A return mapping algorithm for plane stress
