The virtual fields method has been developed for extracting constitutive parameters from full-field measurements provided by optical non-contact techniques for instance.It is based on the principle of virtual work written with some particular virtual fields.This paper can be regarded as a general review summarising some 15 years of developments of this method.The main aspects of the method are first recalled in the case of both linear and non-linear constitutive equations.They are then illustrated by some recent relevant examples.Some studies underway as well as relevant issues to be addressed in the near future are eventually discussed.
