## Nonlinear finite elements/Rate form of hyperelastic laws

Let us now derive rate equations for a hyperelastic material. First elasticity tensor [ edit ] We start off with the relation P = ρ 0   ∂ W ∂ F {\displaystyle {\boldsymbol {P}}=\rho _{0}~{\frac {\partial W}{\partial {\boldsymbol {F}}}}} Then the

## Rootfinding for nonlinear equations

Here we want to solve an equation of the kind f ( x ) = 0 {\displaystyle f(x)=0} . Suppose that there exist α ∈ R {\displaystyle \alpha \in \mathbb {R} } such that f ( α ) = 0 {\displaystyle f(\alpha )=0} . Then we want to construct a sequence
