Monitoring of Inflatable Structures by Using Virtual Image Correlation

Abstract : The VIC method consists in finding the analytical contour by fitting the boundary of the objet in the picture as best as possible. It has been used for shape measurement of an inflatable beam submitted to a transverse wind in the CSTB wind tunnel in Nantes. The principle and the main equations of the method are recalled. The originality of this study is that the equation of the contour is deduced from the analytical expression of the deformation of an inflatable beam under a distributed constant (aerodynamic) load. This acts as a powerful mechanical-based filter and leads straightforwardly to the researched mechanical properties of the textile membrane.
