1. A bench for mechanical characterisation of a thin object including a portion of interest of a given area by application of a compression force according to a given compression axis including:
a frame,
a first compression face,
a movable element that is mobile along the compression axis with respect to the frame and having a second compression face opposite the first compression face,
uprights fixed to the frame,
means for applying a force according to the compression axis and of a determined intensity to the object intended to be located between the first and second compression faces, said force being orthogonal to the first and second compression faces, the means for applying being fixed to said uprights,
at least one force sensor inserted between the movable element and the means for applying a force,
at least one movement sensor disposed to measure movement between the first and second compression faces in a direction of the compression axis,
wherein at least one of the first and second compression faces includes a projecting compression zone of which an area is less than or equal to a portion of interest of the object, and wherein the frame includes a recess surrounding in the frame a thicker frame forming a pedestal supporting the first compression face.
