Crush Analysis

Crush Analysis

Crush Analysis

(OP)
hi there,

I'm trying to crush a hollow cable between two flat plates. I'm using abaqus explicit with S4R elements and a time step of 0.04s for the crushing. My problem is that the plates seem to only crush the cable elements a small way and no matter how much i increase the load (i'm using a velocity..) the displacement remains the same? Does anybody have experience of this? Should i change the contacts from self contact? Any tips or advice at all would be appreciated.

Thanks,
m.

RE: Crush Analysis

Did you try to increase the time spanned by the ABAQUS Step ?

Hi xerf, thanks for the tip. I tried increasing the time and that has helped but i think i may have a contact issues also. The two plates which are crushing the cable come into the correct position and part of the cable is suitable crushed however parts of the cable have not been fully crushed and so are fouling the crushing plates. Do you think i still need to increase the step time? I'm using a surface to surface contact between the plates and cable and also the general contact option for the model...

Thanks in advance.
