Element Stiffness Matrix Formulae for common elements? 1

[bongirs]

Hello,

I am in need of developing a mini-FEA software for my project and need some help in understanding the theoretical aspects of FEM.
Since I do not have the differential equations of the objects, I am restricted to using the strong form approach instead of the weak form.
I tried looking up for element stiffness matrices of common elements like tetrahedron, brick, hex, etc, but without success.
Similar to what we get for 1D elements in most of the books, I need for 3D elements, which I am unable to get.
Is there a book/paper/website or any other which shows the FEM process using these elements.
Or at least a logic for developing the stiffness matrices would also be helpful.

Thank you IDS! The index tells me that this is the book that I have been looking for.

If you are interested in FEA modeling of shells, there is a book supplied with a CD containing complete source codes and a variety of examples:

(the authors also have their own webpage devoted to the book:
