Hi glouvincs01,


 


It is not surprising if you have your first frequency very high because, as you mentioned, all the contact becomes linear bonded contact and all the bodies act as a whole. Imagine you do a modal analysis on the blue body only.


For shock wave propagation problems, I would use an Explicit solver. You can use either Ansys Explicit or Ansys LS-DYNA.
