We develop herein parallel algorithms for the solution to large nonlinear problems. Applications deal with the simulation of hyperelastic incompressible material underlying large deformations and with the study of porous media. The chosen modelizations requiere both displacement and pressure unknown fields.We use a finite element strategy associated with a Newton-Raphson solver and a non-overlapping domain decomposition associated with a Krylov iterative solver.We propose improvements to adapt these approaches to our problems. For more complex cases we define a novel domain decomposition approach, called hybrid approach, which enables to be more respectful with the physics of the phenomena and which unifies the classical approaches. We also...
