1. A bench for mechanically characterizing a thin object by applying a compression force along a given compression axis, comprising:
a frame;
a bottom compression assembly resting on the frame and including a first compression face;
movable equipment that is able to move along the compression axis with respect to the frame and carrying a top compression assembly including a second compression face opposite the first compression face;
uprights secured to the frame;
means for applying a force along the compression axis to the object intended to be located between the first and second compression faces, said force having a given intensity and being orthogonal to the first and second compression faces, the means being secured to said uprights;
at least one force sensor interposed between the movable equipment and the means for applying the force; and
at least one movement sensor disposed so as to measure movement between the first compression face and the second compression face in a direction of the compression axis, wherein
the top compression assembly includes a second compression part carrying the second compression face and a second mounting surrounding the second compression part,
the second compression part and the second mounting are rigidly connected to each other at least in the direction of the compression axis, and have a connection in directions orthogonal to the movement direction, have low rigidity so that a deformation of the second compression part in a plane orthogonal to a compression direction does not deform or only slightly deforms the second mounting, and
the at least one movement sensor measures the movement between the top compression assembly and the bottom compression assembly.
