Hello
brothers
Currently,
I‘m working on the determination of the mechanical properties of carbon nanotubes
for different loading cases using ANSYS software ( i need to use them in my
model). My Finite Element model of graphene and carbon nanotube is working fine with beam188 element, but I have
some technical problems in my simulation. These problem are summarized in
points as follow;
- I want to replace the beam element by two springs (linear torsional spring and nonlinear
stretching spring element). Each spring will produce one type
of deformation in the nanotube. The problem is with the torsional spring that
must be modeled as a zero length element. So, which element can be used in this
case and it can provide a properties for zero length element?
- If there is an element that can be used as it described above, can anyone one help
me to understand the theory of the element?
Thank you
