Can I relate the connector forces in Abaqus/Implicit Dynamic and Abaqus/Explicit Dynamic analysis for the same FE model?
I have done a Dynamic (Implicit Simulation) for a model which is moving 125mm along an axis. The result for the displacement and velocity are showing smooth curve for this analysis.But the acceleration graph is showing lots of noise(peaks and lows). Also since it is a implicit analysis the time points are not exactly matching(The model movement is such that it travels 125mm for 0.8secs and then rests for the remaining 1.2secs),as in the the velocity for the model is not exactly zero at 0.8secs.
So before going for the explicit analysis which will be very time consuming I wanted to confirm whether the connector forces will be more realistic in Abaqus/Explicit and can I relate the connector forces in implicit and explicit analysis?
