Abstract

The purpose of this research is to test Norway spruce specimens with different growth ring orientations weakened by edge-notch until failure. In the experiments the specimens were subjected to 3-point bending, tension and compression tests. In addition, failure mode during loading is investigated using a high-resolution camera. Based on the measurement results the correlation between latewood ratio, ultimate force, ultimate elongation/deflection, calculated moduli, growth ring orientation and diameter of the growth ring at the edge-notch were obtained. Based on the population data of the three tests conducted, only one parameter pair, namely the ratio of latewood to calculated modulus, influences the measurement results to almost the same extent. The other parameter pairs show different values and correlations. © 2023 Statny Drevarsky Vyskumny Ustav. All rights reserved.
