How to give strain loading in ansys explicit dynamics?
I am trying to simulate Hopkinson bar experiment. in simulation i do not want to simulate striker bar. I have the incident strain in incident bar from the experiment. In explicit dynamics, there is no option to give strain as loading. Thus I converted the incident strain to incident stress By linear relation stress = E x Strain, as the long bars remain elastic during experiment. Then I have applied stress value as pressure to the incident bar face where striker strikes. The bars are restricted for displacement in Y and Z direction and free in X-direction (along length).
In results when i plot the strain in the bar, it is not the same value and less then the strain applied as pressure.
Can some one guide me how can i Give strain loading ?
