Abstract
Mathematical modelling is often used to investigate phenomena difficult or impossible to measure experimentally. This paper presents the constants needed to mathematically model green Pinus radiata D.Don core- and outerwood. The constants include all three elastic and shear moduli along with the six Poisson ratios needed for describing orthotropic materials in the elastic domain. Further proportional limit surfaces are presented. The constants provided allow for an increase in realism of mathematical models examining the mechanical performance of standing trees.

Mathematical modelling is often used to investigate phenomena difficult or impossible to measure experimentally
The purpose of this paper is to provide the material constants necessary for describing green coreand outerwood as an orthotropic material
The outerwood boards were of higher dry density and lower micro-fibril angle (MFA), resulting in a higher longitudinal
