From: Comparison of frequency and strain-rate domain mechanical characterization
Strain-rate dependent apparent elastic moduli at the same level of pre-strain (i.e. 3 μm indentation depth), as obtained by nano-\(\dot{\varepsilon }M\) (Eapp,P, orange triangles) and derived from DMA (Eapp,DMA, blue circles). Dashed lines are linear interpolation and only serve as a guide to the eye. Error bars denote standard errors. The inset shows the correlation plot between \({E}_{app,DMA}(\dot{\varepsilon })\) and \({E}_{app,P}(\dot{\varepsilon })\) data (r = 0.99).
