Geometry of an inflated membrane in elliptic bulge tests: Evaluation of an ellipsoidal shape approximation by stereoscopic digital image correlation measurements

Experimental protocols coupling microstructural observations to mechanical loading often require taking strong assumptions about the global geometry of the samples during the tests. It comes from the very local nature of the measurements, since it is often very complicated to combine simultaneous macroscopic and microscopic observations. However, in order to use the structural data obtained on a representative volume element (RVE), the local behavior identified has to be homogenized, and to do so, knowledge about the global behavior of the considered material is needed.
