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

Submitted by akinbala on

Materials Forum

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

 

ill-posed meshfree problem

Hi,

I'm looking to solve a problem in which although the position of a boundary or force-generating constraint is not known, the distance between the constraint and one other (usually a "neighbouring" particle -- whatever neighbour means ;) ) is known.

After much thought, I've concluded that the problem is a constrained energy-minimization problem. In other words, I need to find the arrangment of the particles such that the strain energy of the system is minimized and while constraint between the nodes is satisfied.

Temperature dependence of the thermo-mechanical properties of 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
