Compressive response and failure of balsa wood - ScienceDirect

Balsa wood is a natural cellular material with excellent stiffness-to-weight and strength-to-weight ratios as well as superior energy absorption characteristics. These properties are derived from the microstructure, which consists of long slender cells tracheids with approximately hexagonal crosssections that are arranged axially.

COMPRESSIVE FAILURE OF FIBRE COMPOSITES

Although fibre kinking limits the compressive strength of carbon-matrix composites, and has often been observed in wood, the importance of kinking in metal- matrix and ceramic-matrix composites generally is not yet clear.

Wood Strengths - WoodWorkWeb

A wood strength rating chart by type. Strength may be defined as the ability to resist applied stress: the greater the resistance, the stronger the material. Resistance may be measured in several ways. One is the maximum stress that the material can endure before "failure" occurs.
