Étude numérique et expérimentale du thermoformage d'une plaque de verre

Abstract : This study aims at increasing knowledge on glass forming. This process, studied and developed by the CERFAV, is based on the deformation of glass by increasing temperature within an electric radiant furnace. Two investigation tools were developed in parallel: a computational program dedicated to the numerical simulation, and an original experimental set up.
The rheological viscoelastic model implemented into the MSCMARC© software for mechanics was chosen to describe the behavior of glass at temperature ranging from ambient to 800°C in turn elastic, viscoelastic and viscous.
The coupled code (conduction with radiation), validated for test cases found in the literature, were applied to benchmarks similar to glass forming with no deformation. The radiative home-made RAD2D code based on the Finite Volume Method was adapted to glass and implemented into MSCMARC©.
The experimental part of the study consisted in designing and developing an original set up based on a thermoforming furnace. The no-contact-measurements of vertical displacement and temperature on the upper face of the glass were qualitatively compared to our innovative numerical results. In addition, the furnace was characterized in terms of temperature and fluxes and a determination campaign of the thermomechanical properties of the glass was initiated in order to provide data for the refinement of the model.
To conclude, efficient tools for calculation and measurement were developed in the present study. The first results are convincing and will be supplemented by further investigations.
