Newton-Raphson Method — Lesson 3

This video lesson demonstrates how the iterative Newton-Raphson method can calculate the force–displacement curve for a nonlinear system by making initial stiffness assumptions for a zero-displacement system and subsequently calculating forces and displacements iteratively until the solution converges to within a predefined tolerance of the applied force, Fa.
