Summary :

The DYREFORM project aims to acquire an electronic tensile tester equipped with an integrated force sensor allowing the measurement of compressive or tensile forces. The tensile tester measures other forces depending on the direction of stress such as peeling, shearing, bending, Brinell hardness tests, etc. thanks to the diversity of the proposed accessories and fixings. The data acquisition interface allows the calculation of elastic moduli, coefficient of friction, or Poisson’s ratio.
Mechanical tests are essential step to access to the characteristic quantities of materials at different stages of ageing (artificial or natural), from Young’s modulus to the elastic limit, including stress or resistance to fatigue failure, and this under variable conditions ; the temperature or the loading rate for example. Different materials can be tested: metal specimens, plastics, leather, textiles, non-wovens, paper, ceramics, etc. Whether these materials are reproductions of heritage materials or proposals for new consolidation or filling materials, the study of their mechanical behavior is necessary for their understanding and/or validation.
The acquisition of a laboratory tensile tester, accessible to the entire scientific community and in particular to DIM PAMIR’s members, will permit on the one hand the characterization of specimens, very different in size and nature, and the validation of new treatments and materials used in restoration. And on the other hand, the training of future professionals in conservation-restoration field in the use of this tool, across their training at the INP (PEEX projects, scientific protocols over the final year memoirs, etc.).
