FEM-Analysis and what it can do.

Stresses or deformations, hmm...? FEM - Finite Element Method or FEA - Finite Element Analysis is a numerical method for calculating stresses and deformations in complex geometrical structures.
The structure is divided into so called "finite elements" connected through nodes. The physical facts are described on the basis of initial or boundary conditions for each of the elements concerned. The definitions of all elements are summarised in the global system of equations, which can be solved. FEM is the magic word.
The result is impressive. As a result, strength tests and optimisation can be performed during the initial orthopaedic-implant development phase to save considerable time and a range of biomechanical tests.
