compressive strength parallel to grain

The objective of this study is to compare three nondestructive methods for evaluating the bending modulus of elasticity(MOE),modulus of rupture(MOR) and compressive strength parallel to grain(σ_c) of Eucalyptus grandia×E.

首先采用3种无损检测设备获得无疵小试样的动态弹性模量,然后进行抗弯弹性模量(MOE)、抗弯强度(MOR)和顺纹抗压强度(σc)的测定,并分析3种无损检测结果与木材强度性质的关系。

In the experiments, the principal research is in proceeding timber softening, longitudinal compressing and molding fixing.

在实验中，进行了木材的软化、木材顺纹压缩和弯曲定型，这也是该课题研究的主要方面。

Depending on bending theory and according to the process of wood multi-direction bending, the experiments are carried out about timber soften, longitudinal compressing, multi-direction bending and dryness finalization and mesurate the minimum radius.

在探讨理论依据和弯曲可行性的前提下，按照木材压缩弯曲的流程进行了木材软化、顺纹压缩、多向弯曲和干燥定型实验，测定了最小曲率半径。
