The article considers the granulometric analysis of selected samples of tropical wood dust
from cumaru (Dipteryx odorata), padauk (Pterocarpus soyauxii), ebony (Diospyros …

Needle penetration resistance (NPR), screw withdrawal resistance (SWR), core drilling (CD)
and drilling chips extraction (DCE) are nondestructive and semi-destructive techniques used …

Density values are essential for the characterization of wood elements in existing structures.
A new method for the in-situ density estimation of timber pieces is proposed based on …

Wood density is an important characteristic of wood which correlates to its strength. This
study proposes an algorithm using multiple regression on pre-segmented colour images of …

The physical and mechanical properties are essential to exploring the potential applications
of each wood species. Janka hardness allows us to identify the wood's workability and …

For safety reasons, wood strength values are calculated based on their characteristic values.
Brazilian national standard (NBR, in Portuguese “Norma Brasileira Regulamentadora”) …

To ensure the safety of wooden structures, estimation of wood strength is based on the
characteristic strength values. The Brazilian standard (NBR, in Portuguese Norma Brasileira …

The characteristic value of compressive strength parallel to the grain is used to design
structural members in bridges, houses and buildings. Such value is obtained based on …

This chapter introduces the reader to basic elements of wood anatomy, chemistry and
physical properties, aiming to assist with the understanding of the morphological and …

Density estimation by non-destructive or semi-destructive methods is applied mainly on
softwood species. The instruments are expensive, the methods are complicated and the …
