Outline of Final Research Achievements

In the research, the deformation of a structure was measured quantitatively from stereo photo image by introduction of three-dimensional photogrametric measurement software. Especially, our main purpose are the measurement of the inflatable beam with internal pressure and tip loading, and its prediction by the Finite Element Method. Formulation of the Finite Element Method was performed newly. These goals were achieved mostly. The validity of the three-dimensional image measurement software was also confirmed in deformation measurement of other related inflatable structures.
