This is quite easy in ATENA. You just need to define a cycling loading history. So typically you can define a load case with a prescribed deformation of for instance 0.1 mm. Then when defining the analysis steps you will define that for instance that this load case is applied 10 times with the multiplier 1.0 and after that 10 times with the multiplier -1.0. This will mean that first the analysis with increase the prescribed deformation up to 1 mm and then it will reduce it again to 0.0. If you then define another 10 steps with the multiplier -1.0 you will get a displacement of -1.0 mm. This way you can go on and define as many cycles as you want.

I hope that my answer will clarify this topic. If not let me know here in this forum or directly by email to
