      …most common version of the finite-element method, the domain to be analyzed is divided into cells, or elements, and the displacement field within each element is interpolated in terms of displacements at a few points around the element boundary (and sometimes within it) called nodes. The interpolation is done so…

        …containing many variables made the finite-element method practicable. In this method a complicated structure is divided into a number of separate equilibrium conditions, and strains (or deflections) are rendered compatible, thus leading to a complete analysis of stress and strain distribution throughout the structure. However, computers only model or approximate…

        Known as the finite element method (FEM), this technique was developed by the American engineer Harold Martin and others to help the Boeing Company analyze stress forces on new jet wing designs in the 1950s. FEM is widely used in stress analysis, heat transfer, fluid flow, and torsion…
