I have been studying structural physics lately, in particular the linear elastic eqns, governed by the equation of motion. https://en.wikipedia.org/wiki/Linear_elasticity
I am trying to solve these equations numerically. I was thinking of a scenario of a rod being compressed on one end by some pressure load, say 1kPa. Does this 1kPa load correspond to the external force term in the equation of motion or does it translate to a normal stress, which would be the divergence term in the equation of motion?
