Bending characteristics of hardwood lamellae in the elastic region

This article focuses on the analysis of the effect of certain factors (wood species, degree of densification, material thickness and number of loading cycles) on the modulus of elasticity (MOE), limit of proportionality (LOP) and elastic potential (PE) of beech and aspen wood lamellae measured in the elastic region of the stress-strain curve under bending loading. Beech wood achieved higher MOE, LOP and PE values than aspen wood. As the degree of densification increased, the MOE and LOP also increased, while the PE remains almost unchanged. MOE values increase as the material thickness increases, while the LOP and PE decrease. Cyclic loading caused an increase in the LOP and PE, but it had little effect on the MOE. Cyclic loading had a greater effect on densified wood than non-densified wood.
