Poisson's Ratio & Volumetric Strain
Poisson's Ratio & Volumetric Strain
(OP)
One of our geotech subs has included a graph of axial strain vs. volumetric strain in a triaxial CD test report. I need to calculate poisson's ratio for the material, but I don't think volumetric strain vs. axial strain depicts the same relationship that poisson's ratio is meant to describe (lateral strain vs. axial strain). Is this correct, or is there a way to calculate poisson's ratio?
Thanks!
Thanks!

Vol strain = Z strain - 2 * nu * Z strain
