An approach for adjustment of defects in constitutive models is presented.
First, the parameters in an initial model are determined from a measured dis-
placement field and the residuals are analysed.
If the residuals are unaccept-
able, a set of candidate model extensions is specified.
From this set, the
'best' model extension is selected by performing a sensitivity analysis.
means of numerical simulations, it is shown that this approach can be applied
to find the 'best' model for a class of inhomogeneous materials in a fast way.
To characterise the mechanical behaviour of a material quantitatively, a
constitutive model must be chosen and the parameters in this model must be
