    of the software team of HOLO3 the image correlation software DIC Digital Image Correlation allows from a simple pair of digital cameras to map a very fine displacement field on the surface of a mechanical part or any other object subject to external stress mechanical stress heat It also allows several post treatments such as the creation of virtual gauges profiles Recordings can be made in quasi static mode standard cameras or in dynamic Besides the development of an interface oriented to industrial use a significant effort has been devoted to the metrological aspect The basic information provided by a system is a mapping of movement which is pixel unit The move to millimeter data is achieved through a rigorous calibration phase but still relatively simple to implement The displacements at any point on the surface can easily be measured with a resolution of ten microns for a field analysis of 800x800 mm The other quantity of interest to the designer of a mechanical part is the mechanical strain under stress In the case of DIC it is obtained by derivation of at the first order of the displacement field One can get the complete mapping of all components of the strain tensor Of course wellknow strain gauge has been included in the software CORREL STC this is a virtual gauge that can be place a posteriori after testing at any point the surface and anywanted direction The strain in the direction of the gauge but also provides X Y Z displacement strain in the direction perpendicular to the gauge main directions The metrological aspect of deformation has also been widely studied numerous comparisons between the information gauge virtual and real gauges bonded to the surface showed differences not exceeding 0 02 even for large deformations why real gauges come

  • SATIN Project
    of French and European standards Methods Approaches The project is based on an in depth study of the bread pan interface heat transfer biochemical reactions during baking in order to determine the means to lower the baking temperature and by the way to reduce the risk associated to EC and NFC An automatic baking machine will be developed to carry out ageing tests of anti stick coating in well defined conditions Modeling of the heat transfer between the mould and the bread will allow a better understanding of the temperature evolution at the mould bread interface and of the crust formation Chemical reactions describing crust formation in particular formation of NFC and interactions between polymers of the anti stick coating and of the crust will be developed These approaches will allow a better understanding of the links between the degree of ageing of the anti stick coating the structure of the crust and the presence of EC and NFC In parallel non destructive testing equipments of the anti stick coating based on optical properties will be developed the presence of EC and NFC will be considered to determine the end of the life of the anti stick coating The testing equipments and innovative pans will be implemented in industry conditions two set of prototype baking pans will be tested to assess the degree of ageing of the anti stick coating These results will permit the complete the models and studies carried out on contaminants Results SATIN aims at developing methodologies equipments and technological solutions resulting in the production of healthy and sustainable breads Main expected outcomes More durable anti stick coating solutions will be developed to extend the shelf life of perfluorinated coating for the benefice of the environment and of the health of consumers meanwhile i twill be attempted
