Relation between the dynamic modulus of elasticity and the static modulus of elasticity, the modulus of rupture of mandarin peel–sawdust composite board

Abstract

This study was conducted to determine the relation between the dynamic modulus of elasticity and the static modulus of elasticity, and the relation between the dynamic modulus of elasticity and the modulus of rupture of mandarin peel-sawdust composite boards. The result of this study was as follows: There was highly close linear correlation between the dynamic modulus of elasticity and the static modulus of elasticity, modulus of rupture of the mandarin peel-sawdust composite boards with the density of 0.4, 0.5 and 0.6 g/cm 3 , and the mandarin peel content of 10, 20, 30 and 40%, thus, the static modulus of elasticity and the modulus of rupture can be predicted from the dynamic modulus of elasticity measured by free vibration test using resonance frequency.
