How to use the hybrid/mixed method to solve geometrical nonlinear problems?
It seems the the difficulties are how to choos strss(Cauchy, Lagrange or Kirchhoff ) and the corresponding expression of energy functional. When the large deformation is considered, the equilibrium equation is coupled with the displacements and the complementary energy is different with linear problems.
