Study of the relationship between flatwise and edgewise modulus of elasticity of plantation fibre-managed E. nitens sawn boards

This study investigated the relationship between flatwise and edgewise modulus of elasticity (MoE) of plantation fibre-managed E. nitens sawn boards. 331 boards were used to build a complete picture of this resource by measuring the density, moisture content, and static edgewise MoE. Then, 147 boards were tested for static flatwise MoE. Results showed that average static flatwise MoE is highly linearly related to static edgewise MoE. The average flatwise MoE could be predicted through the linear relationship considering the contribution of the width of the boards. The R2 value of this linear regression formula is 0.9.
