Dear friends
I want to plot force-displacement figure for simulation of axial impact in Abaqus; after using reference points for defining the
displacement and force in tubes and plates , I encounter
two problems:
1) 1)Amount of forces are
negative.
2) 2)I need to filter the figure
because forces have some vibrations in the figure and they are not zero after rebounding;
they have sine form. So, I have to filter them?
Please let me know how to solve
it.
