Why am I not getting a force balance when I use a higher order beam188 element with plasticity?
This is a bug. We are not checking for the unbalanced forces in internal nodes of 188. The effect is exaggerated in your problem due to only one element used. With reduced integration you still get correct reaction force. The workaround is to not use keyopt,(3)=2 for 188 with material nonlinearity. The error is fixed in 11.0. |
