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.

Device and method for measuring the deformations of a sample

A device and method for measuring the deformations of a sample, which deformations particularly result from the relaxation of the stresses to which the samples was previously subjected. The device and method include the use of a cell inside which the sample is placed with the cell containing a thermal mass whose heat capacity and/or thermal conductibility are appreciably greater than those of air under normal temperature and pressure conditions.
