Finite-strain kinematics, constitutive responses and virtual-work forms.

\[ P(F)=\frac{\partial W}{\partial F},\qquad DP(F)[H]=\frac{\partial^2 W}{\partial F^2}:H. \]

A total-Lagrangian hyperelastic model uses a reference domain $\Omega_0$ , displacement $u$ and deformation gradient $F=I+\nabla_0u$ . The stored energy determines the first Piola–Kirchhoff stress and tangent action.
