a The stress-strain curves showing the responses from experiments (green) and simulations (red) superimposed. The Inset shows the stress serrations in magnified view. b The raw subtracted speckle images showing two simultaneous PLC bands. c Two strain rate maps showing the experimental effective strain rate εspec,t (top) for one band inclination and for comparison the difference of plastic strain rate εp,t and applied strain rate εext,t during a simulation done with the same strain rate. Below the relative standard deviation of the plastic strain rate in the simulation
