Fig. 6. Comparison between BOR test and simulation. (a) flexural stress-displacement curve; (b) out-of-plane displacement at different stages; (c) full-field out-of-plane displacement from DIC and simulation.

The comparison between typical BOR and ROR tests and numerical results are shown in Figures 6 and 7 respectively. For both loading conditions, the flexural stress - displacement relation is linear elastic. The
