Generalized cutting force model for peripheral milling of wood, based on the effect of density, uncut chip cross section, grain orientation and tool helix angle [PDF]

, 2021
Article publié en open-access sous accord avec CRUI-CARE (Université de Florence)The influence of the grain angle on the cutting force when milling wood is not yet detailed, apart from particular cases (end-grain, parallel to the grain, or in some rare ...

Predicting wood density of growth increments of Douglas-fir stands in New Zealand

New Zealand Journal of Forestry Science, 2018
Background Douglas-fir comprises 6% of New Zealand’s planted forest area and contributes to the national carbon sequestration estimate. Carbon stock changes in Douglas-fir stem wood can be calculated by multiplying the increment in stem volume under bark

Relationships Between Wood-Anatomical Features and Resistance Drilling Density in Norway Spruce and European Beech

Frontiers in Plant Science, 2022
Environmental conditions affect tree-ring width (TRW), wood structure, and, consequently, wood density, which is one of the main wood quality indicators.

Global patterns of tree wood density [PDF]

Global Change Biology
AbstractWood density is a fundamental property related to tree biomechanics and hydraulic function while playing a crucial role in assessing vegetation carbon stocks by linking volumetric retrieval and a mass estimate. This study provides a high‐resolution map of the global distribution of tree wood density at the 0.01° (~1 km) spatial resolution ...

Functional Relationships Between Branch and Stem Wood Density for Temperate Tree Species in North America

Frontiers in Forests and Global Change, 2020
Wood density is strongly related to key aspects of tree physiological performance. While many studies have examined wood density in different parts of trees, for a variety of reasons, there are very few studies that have compared within-tree density ...

Influence of growth parameters on wood density of Acacia auriculiformis

Maderas: Ciencia y Tecnología, 2022
Understanding the drivers of wood density variation both within a tree and between trees is important in predicting the quality of wood logs and improving this quality through adequate forestry management.

Effects of semi-isostatic densification of wood on the variation in strength properties with density [PDF]

, 2005
The variation in strength properties with density was compared between semi-isostatically densified and non-densified wood. Strength properties were compared with published data from earlier studies using other methods for densification.

Wood density and anatomy of water-limited eucalypts [PDF]

Tree Physiology, 2004
We hypothesized that seedlings grown under water-limited conditions would develop denser wood than seedlings grown under well-watered conditions. Three Eucalyptus species (E. grandis Hill (ex Maiden), E. sideroxylon Cunn. (ex Woolls) and E. occidentalis Endl.) were grown in a temperature-controlled greenhouse for 19 weeks with watering treatments (well-
