Abstract

A device and method are provided for measuring the deformations of a sample, with the deformations resulting more particularly from the relaxation of the stresses to which the samples were subjected prior to the measurement, and with the sample having an axis corresponding to a main deformation direction. The device comprises at least five displacement sensors each having a measurement direction, with the measurement directions being substantially perpendicular to the axis of the sample.
