I'm struggling to understand what boundary conditions actually refer to in the context of computational engineering.
So I have a problem involving a bar that is fixed at one end and struck by a rigid body at the other, sending a compression wave through the length of the bar. I'm asked what are the boundary conditions at the two ends of the bar, but what does this actually mean? And how do I go about calculating it (if there even is any calculation involved)?
I'm given the following values:
bar length = 70mm, bar density = 7900kgm/m3, bar young modulus = 200GPa, rigid body velocity = 20m/s.
Any help is appreciated, thanks
