nodal displacements are the unknowns, it is called the displacement method, and if nodal
forces are the unknowns, it is the force method. For the mixed method, both forces and
displacements are chosen as unknowns.
The finite element method is one of several variational methods (Stein and Wunderlich,
1973) that result in algebraic equations relating undetermined coefficients. Typically,
mechanically significant parameters are used as the unknown coefficients. The response
variables throughout the elements are related to the nodal unknowns with trial functions
