Residual stresses using thermal expansion
Residual stresses using thermal expansion
(OP)
Hello all,
I would like to simulate the procedure of the dipping of a medical tool into liquid nitrogen and measure the amplitude of the residual stresses after that.
Does anybody know any location to find tutorials on how to define two different temperature half-spaces (liquid nitrogen and air) and how to create a "moving" object between those two half-spaces.
I want to see also the effect of the dipping speed, that's why I need the two half-spaces.
Thank you very much!
I hope to reading from you soon!

to assess the effect of dipping speed, just perform a parametric study by varying the velocity of the moving object. one way to do it is to change the velocity and run the job every single time. the automated process will include writing a python script for parametric studies.

Unfortuately Abaqus requires a complete Intel Fortran set-up for compiling user subroutines at runtime. If this poses a problem, you can take a look at CalculiX, a free, open-source non-linear FE solver, which uses the same keywords as Abaqus (a sub-set) and also supports film.f. It compiles with gfortran, so it's easy to do on any Linux system.

1. How can I create a box with a liquid container in it. Also I don't want the temperature of the liquid to change over time.
2. I don't know where or how to find film.f subroutine.
3. Do you know anybody that has done it before so that I can find some kind of tutorial online?
Thank you again.
