Feng,
if you're looking for a rubbery material, you should consider first a suitable strain energy function (SEF) (or stored energy function (SEF), they're the same).
e.g. The simplest SEF is the neo-hookean SEF, which describes the stress strain behaviour well for the first part of your...
Hi FM,
I guess if a part is "movebale" or "fixed" is entirely defined in the boundary conditions. It does not have an effect in which order the parts are added to an assembly.
If you cannot choose a face (probably because your other geometries are complex and hide this certain part) try to...
About the CIN-elements I guess I am ok with them.
As shown in figure "wave2" my 2D model consists of a block with rubbery properties and a rigid slider.
BC's:
The block is constrained in all DOF's on the bottom side, all other sides are unconstrained (as it would be in "real life"). The...
I managed to use CIN-elements (infinite elements) in order to get "quiet" boundaries, which prevents the wave from bouncing back into my model, which is a plus. However, before hitting the infinite elements, the wave still continues throughout the model on the surface.
I am not entirely sure...
I am using Abaqus Explicit (v6.8). According to the help manual, the matrix storage option "unsymmetric" is only available in Standard, is this correct? Do you have another option in mind?
I am trying to change the critical damping factor (by default = 0.03) at the moment.
Hi rstupplebeen,
thanks for the super fast answer. I guess "stabilization" and "matrix storage" all appear on the help manual, right?
I'll have a look for them tomorrow!
Thanks again,
Phil
Dear all,
I am modeling rubber friction at high coefficients (bigger 1.0) and at some point of sliding friction, my model goes somehow unstable and bounces up and down, with waves on the surface. Looks a bit like I modeled a liquid.
Does anybody know how I can change the damping, or put...
just constrain one end of your beam. e.g
Symmetry/Antisymmetry/Encastre
and choose Encastre. It constraints ALL DOF's for the chosen part of your beam. So no U1=U2=U3=UR1=UR2=UR3=0
This is for 3D, but same should apply if you use 2D.
If you apply load in the negative direction, it should...
I know it's lame to push the tread, but I would really like to find out the reason.
Anybody had probably a similar problem, getting 2 different outputs for the same contact situation?
Any kind of slightest hint is greatly appreciated guys
Thanks a lot!
Phil
Hi,
after I somehow lost my user name here, I am back again:
I am modelling indentation of a rigid indenter into an elastomer surface. I defined the frictionless contacting surfaces as surface-to-surface contact (Explicit). Now the problem is that I get two different areas of contact for both...
