Is there any method to estimating the arc length, and a good initial arc increment?..............
I'm conducting a RIKS analysis using Abaqus, the analysis proceeds to a certain point then the inc/LPF values become negative and the analysis terminates when the maximum specified increments are...
Thanks for your quick response,
I think I may have found a solution;
i was trying to introduce a geometric imperfection into the model and it became unstable (even under RIKS analysis). I thought this was probably due to the prestress in the plate from the axial load.
However I am now...
Hi
I am investigating a steel plate shear wall in abaqus using a 2 step analysis (1-axial load, 2-lateral displacement)I am trying to avoid placing prestress on the infill plate under the axial load.
Is there a way to run an abaqus analysis with a specific region in the model "disabled"
thanks
