Abstract
ABSTRACT
In this paper, we present a new error indicator for the frictional contact problem
governed by Coulomb’s law. This indicator is built over the combination of two known
methods. The first concerns the error obtained from the projection techniques where
super convergence properties are used for smoothing the finite element stress fields.
The second method takes into account the errors in the constitutive relation of the
contact zones. By using both the error indicator and procedures of mesh adaptivities,
we show example of optimised computations.
