T.V. Tretiakova et alii, Frattura ed Integrità Strutturale, 27 (2014) 83-97 ; DOI: 10.3221/IGF-ESIS.27.10 92 (a) (b) Figure 13 : Evolution of axial strain (a) and axial strain rate fields (b) due to nucleation of the PLC bands during the time period 7 12 t t  . As clearly shown in Tab. 3, the local axial strain rate is about 80.0 %/min whereas the macroscopic strain rate is 10.0 %/min. The material’s deformation in the area of the localized plastic strain band happens 8 times faster than the specimen deformation.
