Wood Handbook--Chapter 4--Mechanical Properties of Wood

Poisson’s Ratio When a member is loaded axially, the deformation perpen- dicular to the direction of the load is proportional to the deformation parallel to the direction of the load. The ratio of the transverse to axial strain is called Poisson’s ratio. The Poisson’s ratios are denoted by µLR, µRL, µLT, µTL, µRT, and µTR.【Get Price】
