Abstract

We present a new method for the characterisation of the local strain distribution in heterogeneous materials. It is based on the adaptation of statistical techniques for the morphological characterisation by two-points covariance to local strain fields measured by means of SEM microextensometry. It permits us to show that the mechanical behaviour is not only the consequence of very local heterogeneities of behaviour between neighbouring grains or phase domains, but also strongly depends on long range interactions.
