This how task goes: i need to find deformation and stress of piston in moment of hit between piston and tool (tool is stationary). Velocity of a piston is (5-7 m/s) and forces are in picture below. I was analyzing it in "Transient Structural" because of a low velocities, but it seems not to work out.
Why i can't fixate a tool by "Fixed Support" or "Displacement" (i can't choose any geometry)?
Do i need to make any "Contact" or "Body Interaction"?
What time to put for a solution? (I didn't quite understand this part)
