Abstract

There are more than 1000 wood species worldwide available that have the potential to be used in structural applications. Many of these species are tropical hardwood species. In this paper, the mechanical and physical properties of a large number of tropical hardwoods are presented. They are investigated for relationships that are valid for all tropical hardwood species based on non-destructive measurable parameters. It is found that slope of grain and density can be used to describe the relationship between the mechanical properties of the entire dataset. However, slope of grain is difficult to identify and measure in practice. The dynamic modulus of elasticity in combination with density can be used as grading parameters on the basis of which a species can be assigned to multiple strength classes.
