The paper broadly surveys work done by the author and his collaborators on variational methods applied to nonlinear problems, especially to the Navier Stokes equations, to transonic flow of compressible inviscid fluids and to deformations of hyperelastic materials. The techniques considered are finite elements, continuation, penalty, alternating directions, and augmented Lagrangian methods. For proofs and details, the reader is recommended to see the author [Numerical methods for nonlinear variational problems (1984; Zbl 0536.65054)] and the author and M. Fortin (eds.) [Méthodes de lagrangien augmenté. Applications à la résolution numérique des problèmes aux limites (1982; Zbl 0491.65036)].
