| Tóm tắt≠ | The Modulus of Rupture (MOR) and Modulus of Elasticity (MOE) are standardized measures of wood mechanical properties determined through static bending tests. MOR quantifies the maximum bending stress wood can withstand before failure; MOE measures stiffness (resistance to bending). These are fundamental properties used for wood grading, structural design, and assessment of wood quality and species suitability for applications requiring strength or stiffness. | X-ray densitometry is a nondestructive method for measuring wood density, microdensity profiles, and ring-by-ring density variation in wood samples using X-ray image analysis. The method uses attenuation of X-rays passing through wood to quantify mass per unit volume. It enables rapid assessment of wood quality without destroying material, making it valuable for research, timber grading, and genetic selection programs. |
