cyclic test of masonry

[Zamiad]

Hi,

I’m running an analysis on a 3d masonry wall under cyclic loading. My issue is that, even after adjusting solver tolerances, switching solver methods, time steps and trying other analysis settings, the analysis fails to complete all the loading cycles. In the attached figure, the dashed line represents the experimental backbone curve I’m attempting to reproduce in STKO. However, the simulation stops mid-cycle due to convergence issues after a certain step. I appreciate if you can help how I can proceed.

Also, I would appreciate it if there is any sample file with the same scope and a 3d model that you can share.

Thanks,

Without the model is difficult to tell where the problem might be

Thank you, would it be possible if you could refer us any sample file? Also for a 3d wall cyclic test, do you think Load Control Integrator is okay?

Thanks for your help,
