Blurred constitutive laws and bipotential convex covers
In many practical situations, incertitudes affect the mechanical behaviour
that is given by a family of graphs instead of a single one. In this paper, we
show how the bipotential method is able to capture such blurred constitutive
laws, using bipotential convex covers
Synergies between the constitutive relation error concept and PGD model reduction for simplified V&V procedures
A hybridized mixed finite element domain decomposed method for two dimensional magnetotelluric modelling
Convergence of a finite element method based on the dual variational formulation
summary:An "equilibrium model" with piecewise linear polynomials on triangular clements applied to the solution of a mixed boundary value problem for a second order elliptic equation is studied.
The procedure is proved to be second order correct in (the maximal side in the triangulation) provided the exact solution is sufficiently smooth
