## 3.8 Newton-Raphson Method

The Newton-Raphson method (also known as “Newton's method”, “Full Newton method” or “the Newton method”) is the basis for solving the nonlinear finite element equations. This section will describe the Full Newton method and the Broyden-Fletcher-Goldfarb-Shanno (BFGS) method [55]. The latter variation is actually a quasi-Newton method. It is important since it provides several advantages over the full Newton method and it is this method that is implemented in FEBio [55].
