Need Volumetric strian vs effective shear strain curves

[ardalannorouzi]

Hello Dear Engineers

I need the data points of Volumetric strain vs. effective shear strain by Tokimatsu and Seed (1987), This curves used in liquefaction computing of soils.

I Found the paper and image of the curve and attached here but I couldn't found any data points.

Would you please provide me with the data points of this curves?

Thanks

Yours faithfully
