Evidence of residual stress in small sections of ordinary green Eucalyptus regnans

Wood Science and Technology Aims and scope Submit manuscript

Summary

Conclusive evidence is offered to show the existence of significant residual elastic stress in the form of alternate layers of tension and compression in relatively small pieces of normal green eucalyptus wood. A method of detecting residual stress in small samples of wood is described, and the stress distribution approximated from deflection measurements following a formula widely used in the science of metallurgy.
