Cyclic Jump Technique - UEL - Abaqus
In my current work, I am trying to integrate the “Cyclic Jump Technique” as introduced back then in 2006 from Cojocaru by modifying my UEL Subroutine.
The methodology is as following.
- An initial simulation for 6 cycles is executed.
- Then I extract from the ".odb" at last frame [end] the Displacements and Internal Variables.
- Thereafter the second simulation is initiated, where it contains two Loading Steps. In the first step the Extracted Displacement is applied as displacement control load case and at the last increment of the first step the extracted State Variables are imposed.
- This allowed me that the second Loading step of the second simulation has as an Initial State the predefined extracted Displacements and Internal Variables.
The issue now arises at the very first incremental step (KINC=1) for the second loading step of the second simulation.
Even though the original simulation faces no converges issues, when I use the transfer data approach for some reason Abaqus in the second simulation in order to converge sets the original displacments that I imposed back to zero, as you can see on the image on left side (more Images in the attachment as a .zip file), with no load transfer within the elements hence lack of continuity.
Have you ever occured such a similar case within Abaqus Framework?
