| Fig. 3. Nominal tensile stress–nominal strain curves of the notched samples NTS-1 and NTS-3 and the unnotched sample UNTS of Vit-105 MG. Inset shows an enlarged curve at the plastic deformation stage of NTS-1 sample. For notched samples, the nominal tensile stress is defined as the ratio of load F divided by the reduced cross sectional area w eff × t , while for unnotched sample it is the engineering stress. |
