Abstract
This paper presents an application of deflectometry to measure the deformation of a thin cylindrical shell in bending. The principle of the calibration method is briefly outlined. Then, the experimental set-up is presented, followed by comparison of slopes, deflections and curvatures with results from a finite element model of the test. The results are satisfactory though limited by the quality of the reflective surface of the test samples. Future work will focus on more complex shapes to extend the technique.
