SUMMARY
This discussion focuses on calculating internal forces in geometrically nonlinear finite element methods (FEM). The internal forces at each node must equal the external forces, and these forces are derived from variables representing unknown data. The specific formulas for calculating these internal forces depend on the relationship between the forces and the properties of the nonlinear solid being analyzed.
