    Hi,
     
    The vibrations are due to loading being applied using step (jagged) functions. If we differentiate the displacement and velocity functions we get high accelerations leading to large forces and vibrations. To avoid vibrations the functions should be smooth and/or Dynamic relaxation (/DYREL) or Rayleigh damping (/DAMP) could be used.

    sorry about that

    You should subtract the elastic strain (0.000799994) to get only plastic strains. So the table should be:
    0 @ 152
    0.002481 @ 228
    and so on
     
    It is odd the plastic strain is not visible- can you share the model?
     
    Attached is an example of law 36 with plastic strain.
