split hopkinson pressure bar
split hopkinson pressure bar
(OP)
im currently doing FEM analysis on split hopkinson pressure bar compression testing using abaqus. Below is some problem that im facing now:-
1. i do not know how to apply a nonuniform velocity on the striker bar.
2. The elastic wave i generated on the input bar does not contain reflected wave.

RE: split hopkinson pressure bar
If you mean non-uniform velocity with respects to location on a model, you will likely need to employ a subroutine - I understand this is using DISP (this method can also be used to create a time-based + location based non-uniform input).
Hope this helps
