Abstract: A system for measuring a bending deformation of a surface of a material which cooperates with a bending test machine to deform a test piece. The system includes a first portion with lateral teeth which bear against an upper surface of the test piece. A first load support connected to the lateral teeth applies a constant force towards the test piece. A second portion with a central tooth bears against the upper surface. A second load support connected to the central tooth applies a constant force oriented towards the test piece. A measuring device includes a deformation sensor having a first arm connected to the first portion, and a second arm connected to the second portion. The first arm and the second arm are separated from each other by a variable distance (?B) measured by the measuring device.
