Fig. 7From: Time dependence of Poisson’s effect in wood III: asymmetry of three-dimensional viscoelastic compliance matrix of Japanese cypressHourly averages of all the specimens for the off-diagonal elements in the non-shear viscoelastic compliance matrix, measured during creep. Comparison of Q ij (t) and Q ji (t). Q ij (t) is defined in Eq. 4. Error bars standard deviationsBack to article page
