Title: DEVICE FOR MEASURING ENDOGENOUS DEFORMATIONS
Abstract:
Device for measuring endogenous deformations of a structure (1) of materials, during the passage of said structure from a liquid phase to a solid phase, comprising: a uniaxial test body (5) suitable for being embedded in the structure; a deformation-measuring fibre (7) attached to the interior of the test body; and a system (9, 10, 11) that is connected to the measuring fibre (7) and suitable for detecting signals representative of the deformations of the measuring fibre and for determining endogenous deformations from these signals and known mechanical properties of the materials of the test body (5), the test body having a rigidity comprised between 2 and 5 gigapascals.
