Identification of Material Properties using FEMU: Application to the Open Hole Tensile Test
Résumé
This article presents an application of identification via finite elements model update (FEMU) to experimental fields of a plate with a hole using stereo correlation. The presentation includes the evolution of material properties during a tension test, and a first approach in estimating statistical confidence intervals from a single experimental field. These are accomplished by characterizing the material at different load cases, and by repeating the identification multiple times for random samplings of the full field and for random redistributions of noise.
