Frictionless compression tests ( Fig . 25 ) permit the accurate measurement of
Poisson ratio . Typical results of Ep and density vs . – Ez are given in Fig . 30 .
Because the density increases during compression , the Poisson ratio also
increases .

For uniaxial compression , the applied strain increment is dɛ , while the
transverse strains are dez = dɛz = – vdɛj . In this case , dĒ = dɛ , from Eq . ( 21 ) .
Likewise the applied stress 01 , with 02 = 03 = 0 , substituted in Eq . ( 17 ) , gives
01 = f ...
