HOW TO APPLY THE OUT-OF-PLANE CYCLIC LOADING PROTOCOL IN THE LS DYNA

      HELLO everyone.

      I am modelling masonry wall in LS DYNA. Airbags (inflate and deflect) were used to apply the displacement out-of-plane loading on the wall in a semi-cyclic manner. I have recently been trying to replicate the experiment setup using the LS DYNA, as shown in the image; however, I am having difficulty applying the loading protocol. I do not know which LS DYNA keyword to use for the application of the out-of-plane loading protocol. The airbags, when inflated, provide a spatially uniformly distributed loading on the wall. I know that the loading protocol can be applied using the BOUNDARY_PRESCRIBED_MOTION keyword for the In-plane loading simulation. I would be glad to know the LS DYNA keywords or methods to apply the loading successfully?
