摘要: <正>采用单边切口试件进行三点弯曲试验,以测定木材断裂韧性K_(IC)值;同时探讨了试件厚度对K_(IC)的影响。结果表明:(1)本文采用的实验方法是可行的;(2)试件厚度对K_(IC)值无显著影响,但以薄试件为好。

Abstract: Three-point-bending specimens with edge crack were used to measure wood fracture toughness KIC and to analyse the effect of specimens’ width on KIC. The experiment results showed that (1): the experimental method is feasible (2): the width of specimens has no sufficient effect on KIC, so the thin specimens were better used.
