I come from a Computer Science background and I've been around searching for a concise tutorial that tells me how Finite Element Method is used to solve a certain partial differential equation. Unfortunately I was depressed with the large number of advanced studies and papers that assumed prior knowledge.

Is it possible to understand the entire process of implementing FEM easily?

    Just glancing at it, this doesn't seem to be of elliptic type, though it is a linear PDE. I'm assuming constants $E,I,\mu$ are positive. You should also have some boundary/initial conditions specified. If it is of hyperbolic type (as I suspect), then you may still be able to give a FEM approximation, though typically one might apply a finite element approach in the "space" variable and a finite difference stepping approach in the "time" dimension.2012-01-03

After a lot of search, I found this excellent crash course:
